ChuckandClaude Opus 5.5 b8c01c69fb ci: mypy ratchet -- keep type-clean modules clean (71 modules, 536 -> 442 errors) (#661) 
* ci: mypy ratchet -- keep type-clean modules clean

mypy-clean.txt lists the 71 modules under src/ that type-check clean;
scripts/check_types.py runs mypy (--follow-imports=silent) on exactly
those files and fails on any error or a missing/unsorted/duplicate entry.
A new "Type check (mypy ratchet)" CI job runs it with mypy 1.20.2 and
pinned stubs; the manual pre-commit mypy hook now runs the same script
(a local hook, so mypy sees the installed requirements like CI does).

35 modules were made clean with annotation-only fixes: hints, typing.cast,
TYPE_CHECKING imports, implicit-Optional defaults made explicit, and
annotations widened (never guards removed) where mypy called a defensive
isinstance check unreachable. No runtime behaviour change.

mypy.ini: numpy and orjson are treated as Any (follow_imports=skip, also
for stubs). numpy 2.3+ stubs use 3.12 `type` statements that mypy won't
parse at python_version 3.10, and orjson is optional, so seeing its stubs
made the result depend on whether it was installed.

ChuckandClaude Opus 5.5 b518c51679 fix(plugin-system): load/enable failures, atomic state files, pip lock, test-double parity (#645) 
- load_plugin: an on_enable() that raises unregisters the instance, so the
  next load retries instead of returning True "already loaded".
- get_plugin_info: guard plugin.get_info(); one plugin raising no longer
  breaks /api/v3/plugins/installed.
- plugin_state.json and the operation history are written with
  atomic_write_text under their lock.
- plugin_loader: module-level lock serialises pip installs across the
  parallel startup loaders.
- store_manager._install_via_download: extract dir cleanup moved to finally.
- Test doubles: draw_image() warns (DeprecationWarning; the real
  DisplayManager has none), MockDisplayManager.draw_text accepts the real
  signature's optional params, VisualTestDisplayManager logs draw errors at
  WARNING.
- Docs/comments: compatibility.py method name, PluginState.LOADED meaning,
  brittle schema count, why _report_skip_once uses setdefault.
- Remove unused PluginOperationQueue.get_active_operations().

ChuckandClaude Opus 5.5 9964dd2183 feat(vegas): render plugin content off the render thread, and keep it off the GIL when the panel needs it (#630) 
DisplayManager.offscreen() gives a thread its own canvas, so Vegas renders every plugin's ticker content on its prefetch thread instead of pausing the scroll for canvas-bound plugins on the render thread. A render gate (src/common/render_gate.py, vegas_scroll.prefetch_gate, on by default with the GIL-releasing binding) lets the prefetch thread run Python only while the render thread waits in SwapOnVSync: on hdpi, frames 2+ refreshes late fell eightfold and late frames overall from 0.90% to 0.60%. See docs/OFFSCREEN_RENDERING.md.

ChuckandClaude Opus 5.5 afe9001aed refactor(fonts): one BDF loader and one BDF rasterizer (#627) 
* refactor(fonts): one BDF loader and one BDF rasterizer

BDF faces were loaded three ways (FontManager._load_bdf_font,
element_style._load_bdf, DisplayManager._load_fonts) and drawn by two
copies of the same per-pixel loop (DisplayManager._draw_bdf_text and the
plugin test harness's "replicated" copy), which golden images and
check_plugin/dev_server previews rely on matching the panel.

src/common/bdf_font.py now owns both:
- load_bdf_face(path, size) -> (face, realised_px): native-strike fallback
  for sizes the file lacks, one bounded LRU cache keyed on path, size and
  mtime. FontManager, element_style and DisplayManager delegate to it;
  read_bdf_native_size moves here (the old names delegate).
- draw_bdf_text(draw, text, x, y, face, color, clip): builds each glyph as
  a 1-bit mask and fills it with ImageDraw.bitmap instead of a draw.point
  per pixel. A blending Draw (RGB image, "RGBA" mode) keeps the point path
  so translucent colours still blend.

Pixel-identical: 220,032 renders (every bundled BDF at native and
off-strike sizes, 14 strings, 4 colours, clipped on every edge, through
each old loader x rasterizer) match origin/main byte for byte.
test/test_bdf_font.py keeps a lightweight version against a frozen copy of
the old loop. DisplayManager._draw_bdf_text goes from 1.4-23 ms to about
0.1 ms per string (the old loop re-read FreeType's buffer as a Python list
for every pixel).

* fix(testing): harness calendar_font is sized like the panel's

VisualTestDisplayManager built its 5x7 calendar_font / bdf_5x7_font as a
bare freetype.Face. With no size set its ascender reads 0, so BDF text
drawn with it landed 6px above where DisplayManager draws it -- entirely
off the canvas at y=0 -- and get_font_height() returned 0. Golden images
and check_plugin / dev_server previews showed text the panel does not.

Load it through load_bdf_face at the panel's 7px, so it is the very face
DisplayManager uses. Across the differential run this changes only the
cases drawn with the harness's own calendar_font (968 of 220,032), which
now match the panel's output.

* fix(fonts): one BDF face per thread

The shared face cache now hands every loader (FontManager, element_style,
DisplayManager, the harness) the same freetype.Face. FreeType does not allow
two threads to use one face at once, since load_char rewrites its glyph
slot, so key the cache by thread as well.

ChuckandClaude Opus 5 116abb0daa fix: September 16 core audit — partial saves, asset path safety, auto-update, display settings the library refuses, scroll speed (#595) 
* fix(sports): share the ESPN rejected-range memo with the background service

BackgroundDataService always sent a season range first and, on a 400,
fell back to chunks without recording the rejection, so every background
season fetch spent a doomed request and live scoreboards learned nothing
from it (or it from them). The worker now consults and sets the same
6-hour memo fetch_espn_scoreboard() uses: a known rejection goes straight
to month/day chunks, and if every chunk fails the range is asked once for
a real error without re-spending the chunks.

* fix(web): keep plugin asset and action routes inside their directories

POST /plugins/assets/upload, GET /plugins/assets/list and POST
/plugins/assets/delete joined the request's plugin_id onto assets/plugins
unchecked, so '../../config' created, wrote, listed and deleted outside
it. #561 guarded only the route that serves the files. All three now go
through path_safety.resolve_under and answer 400 for anything but a
plain name, and delete only unlinks a metadata path that resolves into
that plugin's uploads directory.

PluginManager.get_plugin_directory refuses ids that are not one plain
path segment, so /plugins/action (which runs a manifest script from the
returned directory) and every other caller get the guard; the action
route also rejects such ids up front, covering its no-manager fallback.

* fix(web): report a no-op plugin update as already up to date

update_plugin() returns True both for a real update and for "nothing to
do" (a ZIP-installed monorepo plugin already at the registry version, a
bundled plugin). With no git commit to compare, POST /plugins/update
called every such success "updated successfully", so Check & Update All
counted most official plugins as updated on every run.

The route now reads what changed off the plugin itself (commit, else
manifest version, else last_updated) and returns data.update_status
(updated / up_to_date / local_only). The update-all toast is summarised
by PluginInstallManager.summarizeUpdateResults from that status, falling
back to the message for older servers.

* fix(sports): scoreboard scroll speed no longer follows target_fps

sports_scroll computed the crisp speed ladder against the global
target_fps whenever limit_refresh_rate_hz was the 100 Hz default. Since
frame-locked presentation (#545) the helper steps a fixed number of whole
pixels per presented frame and the panel presents at its real refresh, so
the General tab's "Scroll Frame Rate" became a speed multiplier: 60 ran a
50 px/s scoreboard at 100 px/s, 200 ran it at 25 px/s.

The ladder now uses the display manager's refresh_hz, then
display.hardware.limit_refresh_rate_hz, then the default. target_fps is
not consulted. Docstrings now say scroll_delay is ignored for pacing (no
behaviour change there) and describe the fixed-step model.

Tests: replace the tests that pinned target_fps as the ladder refresh and
described time-based stepping; assert speed independence from target_fps
(unit and end-to-end presented px/s against the real helper), that the
fixed per-frame step is applied, and that scroll_delay does not change
speed.

* fix(web): escape registry and upload values in plugin manager inline handlers

The store, saved-repository and custom-registry buttons built
onclick='...(${JSON.stringify(id)})...'. JSON.stringify leaves ' alone,
so a custom registry entry whose id contained ' closed the attribute and
added its own handler. One helper, jsStringAttr(), now HTML-escapes the
JSON literal for every one of those handlers, and the store View button
opens only http(s) repo links.

The live window.updateImageList (plugins_manager.js loads last, so its
copy wins over the file-upload widget's) wrote the uploaded file's
original name, path and ids into markup raw; they are escaped now.

* fix(update): let the root pip wrapper install web_interface/requirements.txt

Update Code, the automatic update's health check and Install Base
Requirements install web_interface/requirements.txt through
safe_pip_install.sh, which only allowed the root requirements.txt. The
first commit changing that file would fail its dependency install, and
the automatic updater rolls back any update whose dependencies did not
install -- on every device, for every newer commit.

The wrapper now lists both core requirement files. Only their folders
are resolved, so a requirements.txt symlinked out of the project is
compared by its target and refused (previously the root file's own
symlink target was what got allowed). The updater's file list is a
named constant, and a test runs the real wrapper (pip stubbed) on
every file Update Code and the rollback install.

* fix(web): do not retry plugin requests that got an HTTP answer

PluginAPI.request wrapped everything that was not a structured error as
NETWORK_ERROR: a proxy's 502 HTML page (response.json() throws) and a
JSON error without error_code included. Check & Update All retries
NETWORK_ERROR, so those updates were re-sent five more times with
backoff, contrary to the #587 contract that an HTTP error response is
the server's answer.

NETWORK_ERROR now means only that fetch() rejected. Any HTTP response
without an error_code, or with a body that is not JSON, is API_ERROR
with the HTTP status attached. Tested against the shipped api_client.js.

* fix(scroll): restart the stats window when an idle gap is dropped by size

#582 dropped an idle gap from the frame stats two ways: the reset_scroll()
sentinel, which also restarts the 5s window timer, and a size guard for
scrollers that never call reset_scroll(), which did not. On that path the
first real frame after the gap found the boundary overdue and logged a
stats line for a one-frame window. Both paths now share one seeding helper.

* fix(update): leave plugins alone when update_core's own rollback fails

update_core returns rollback_failed directly when a partial pull or an
update whose health check never started cannot be rolled back. run()
only held plugins back for 'verifying', so those devices still got new
plugin versions and a display restart on top of a core in an unknown
state -- the opposite of what the health-check path does, and of the
3.4.0 changelog (plugins are left alone if the rollback fails).

* docs(api): make the REST reference match the api_v3 package

Every documented request body, query parameter and response shape was
re-checked against the handlers in web_interface/blueprints/api_v3/.
Fixes calls that failed as documented (repo_url, action_id/params,
files/image_id, font_file+font_family, ?font=, cache key,
auto_enable_ap_mode, plugin limit keys), removes the font-override
endpoints dropped in #566, corrects response shapes (plugins/config,
plugins/schema, health, metrics, operation history, github-status,
fonts/catalog, cache/list, logs, wifi, on-demand, SSE streams), and adds
the 26 routes it omitted (backup, system auto-update/git, wifi radio,
starlark editor, MQTT bridge, status endpoints, skins).

Documents the merge semantics of partial JSON saves to /config/main and
/plugins/config and the dim-schedule POST accepting GET's days shape,
which land in the same change set. Replaces app.py line numbers and the
removed api_v3.py path with file and function names.

* fix(web): remove the General-tab plugin system toggles that did nothing

plugin_system.auto_discover, auto_load_enabled and development_mode had
General-tab toggles whose help tips promised dormant plugins and verbose
logging, but nothing reads them: every enabled plugin is discovered and
loaded regardless. Remove the three toggles.

The keys stay tolerated in stored configs. The save handler now stores
a flag only when a client sends it; treating a missing key as an
unchecked box would otherwise rewrite all three to false on every
General-tab save, which still posts plugins_directory.

* refactor(scroll): remove dead code left by #523/#570

- Drop the optional scipy.ndimage import and HAS_SCIPY; nothing read
  them since the numpy blend replaced the scipy path.
- Drop ScrollHelper._last_integer_position and frame_time_target, which
  were written but never read.
- Keep target_fps and set_target_fps() but document them as
  informational: nothing paces off them, yet ledmatrix-elections'
  test_scroll_pacing.py reads helper.target_fps back and third-party
  plugins may call the setter.
- Fix stale comments: fixed_pixels_per_frame's "use scroll_delay to
  throttle", set_sub_pixel_scrolling's "default: True", and
  set_frame_based_scrolling's claim that it steps.

The plugins monorepo was grepped for every removed name; none is used.

* docs(fonts): point plugins at plugin_manager.font_manager; drop removed overrides UI

FONT_MANAGER.md told plugins to read display_manager.font_manager, which
does not exist, so a plugin following it failed to load with
AttributeError. The shared FontManager lives on the PluginManager and
BasePlugin._get_font_manager() returns it (with a fallback for harnesses).

Also removes the Fonts-tab override workflow and element-override panels
that #566 deleted, from FONT_MANAGER.md and WEB_INTERFACE_GUIDE.md.

* docs(store): search via /plugins/store/list?query=; send Content-Type on registry curls

/plugins/store/search does not exist (404) and the list endpoint reads
query, not q. The registry guide's curl examples omitted the JSON
Content-Type, so the handlers saw an empty body and answered 400.

* fix(config): use the shared core-key list in the last three private copies

StartupValidator warned "Plugin 'auto_update' is enabled but not found" on
every display start with auto-update or a dim schedule on; the reserved
plugin-id check missed auto_update, sync, location and the rest; and
ConfigManager's (uncalled) orphan cleanup would have deleted display,
schedule and auto_update. All three now read src/core_config_keys.py, which
also gains CORE_SECRETS_KEYS for the github/youtube secrets sections.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(web): partial JSON saves to /config/main change only what they send

A JSON body with one field reset every checkbox in the sections it touched:
the MQTT bridge's brightness slider turned off disable_hardware_pulsing,
inverse_colors, show_refresh_rate and use_short_date_format, and a
timezone-only save turned off web-UI autostart and weekly auto-updates.
Missing-means-unchecked now applies only to form posts: form-encoded bodies
and the v3 forms, which mark themselves with a hidden __form_section input.

Also on the config routes:
- vegas_min/max_cycle_duration no longer match the generic *_duration rule,
  so they stop landing in display_durations and a blank one no longer
  rejects the whole Display save;
- saving from the Raw JSON editor calls start_setup_if_needed like the
  General form, so enabling auto-update there finishes its setup;
- the schedule and dim-schedule POSTs accept the per-day days.<day> shape
  their GETs return, as well as the flat form keys.

* fix(scripts): install plugin dependencies from the configured plugins directory

install_plugin_dependencies.sh scanned only plugins/, but the Plugin
Store installs into plugin_system.plugins_directory (default
plugin-repos), so the documented "Recommended" fix found 0 plugins on
every store install. It now reads plugins_directory from
config/config.json (relative to the project root or absolute, default
plugin-repos) and also scans plugins/ for dev symlinks, installing a
plugin reached through both only once.

With set -e alone, `pip ... | tee` took tee's exit status, so a failed
pip install was reported as success; set -o pipefail.

* docs: replace stale API names, line numbers and the api_v3.py path

- ADVANCED_FEATURES: StreamManager methods that exist
  (get_next_segment, take_next_group, refresh, advance_cycle, ...), and the
  real on-demand status envelope ({status, data: {state, service}})
- app.py:199 / :144 / :607-619 line citations and
  web_interface/blueprints/api_v3.py (now a package) replaced with file and
  function names in ADVANCED_FEATURES, CONFIG_DEBUGGING,
  PLUGIN_ARCHITECTURE_SPEC, PLUGIN_QUICK_REFERENCE,
  PLUGIN_CONFIGURATION_TABS, TROUBLESHOOTING and web_interface/README
- CONFIG_DEBUGGING: partial /config/main saves change only sent keys; use
  /config/raw/main to replace the file; describe where validation runs
- TROUBLESHOOTING: clear_cache.py needs --clear-all (no args only prints
  usage)

* fix(scripts): verify the web interface that actually ships, on port 5000

verify_installation.sh failed every healthy install: it required the
long-removed web_interface_v2.py and looked for a listener on port 5001,
while the web interface binds 5000 (web_interface/start.py). It now
checks the files ledmatrix-web.service runs (start_web_conditionally.py,
web_interface/start.py, app.py) and port 5000. verify_web_ui.sh had the
same 5001 port in its listen check, HTTP probe and printed URLs.

Port matches are anchored so :50001 no longer counts as :5000.

* docs(plugins): one display-size contract: display_manager.width/height

CLAUDE.md (#580) says to read display_manager.width/height because
matrix is None when hardware init fails; the development guide, the
safety-harness doc and two DisplayManager docstrings still recommended
matrix.width/height. The bundled starlark-apps plugin read matrix.width
unguarded, so its magnify recommendation and frame scaling raised in
fallback mode (e.g. after the Pi 5 hardware refusal).

* fix(install): make install_service.sh --help print usage instead of installing

install_service.sh parsed no arguments, so `sudo ./scripts/install/
install_service.sh --help` (presented as harmless in MIGRATION_GUIDE.md)
rewrote ledmatrix.service, ledmatrix-web.service and both update-verify
units and enabled/started them. It now handles -h/--help (usage, exit 0,
no changes) and rejects any other argument with exit 2 before doing
anything. Running it with no arguments, as first_time_install.sh does,
is unchanged.

* docs(scroll): describe the fixed-step model and document frame_hold

Since #545 a crisp speed from scroll_config.configure() makes the helper
advance a fixed whole-pixel step per presented frame with no clock, and the
display manager's frame hold is part of the speed. The docs still described
the removed wall-clock model:

- scroll_config's module and configure() docstrings said speed is applied
  in time-based mode and that omitting the hold "falls back to fractional
  pixels"; omitting it actually runs the scroll frame_hold times too fast.
- SCROLL_PERFORMANCE.md said ScrollHelper accumulates elapsed time in both
  modes, and read a 20 ms stats median as missed refreshes although that
  is a healthy 50 px/s (hold 2) scroll. It now explains the fixed step,
  the hold-dependent healthy median, that target_fps plays no part, and
  that a hand-added scroll_pixels_per_second loses to a schema-default pair.
- PLUGIN_API_REFERENCE.md documented set_scrolling_state(is_scrolling)
  without frame_hold; it now documents the parameter (core 3.4.0) with a
  configure() + set_scrolling_state example.
- update_scroll_position/set_scroll_speed and set_scrolling_state
  docstrings say the same.

* docs(config): mark target_fps legacy; describe what Vegas scroll_delay does

- General tab "Scroll Frame Rate" (target_fps) is labelled legacy: after
  the sports_scroll fix nothing in core scrolling reads it. The field and
  its API validation stay so saved configs and plugins that read
  global_config['target_fps'] keep working. CONFIG_REFERENCE says the same.
- Vegas frame_based_scrolling/scroll_delay were described as frame-count
  stepping at ~50 FPS. Neither steps nor sets a frame rate: frame-based
  mode converts the speed to px per scroll_delay, clamps it to 0.1-5, and
  still advances by elapsed time, so the applied speed is
  clamp(scroll_speed * scroll_delay, 0.1, 5) / scroll_delay px/s. The
  config comments, render_pipeline comment and CONFIG_REFERENCE rows now
  say so. No behaviour change.

* docs(deps): describe how plugin dependencies are really installed

The guides said the web service runs as root, that installs pick --user
from os.geteuid(), and quoted a warning and a
PluginManager._install_plugin_dependencies() method that don't exist. The
web unit runs as the installing user; store installs go through
install_requirements_file() and sudo safe_pip_install.sh (root), with a
user-level fallback that says so, and load-time installs run in the
display service's own (root) interpreter.

Manual paths now use the configured plugins directory (plugin-repos/ by
default) instead of plugins/, which store installs no longer use, and
install_plugin_dependencies.sh is described as scanning that directory.

* fix(update): count local changes one way for the preflight and the pull

The automatic update's preflight ignored mode-only changes and anything
whose status line contained plugins/ or plugin-repos/, then promised
"Automatic updates will not stash your changes". perform_core_update
used plain git status (modes count) and ignored only 'plugins/', then
ran 'git stash push -- :!plugins', which nothing ever pops. So an edit
to a bundled plugin under plugin-repos/, or the installer's chmods on
tracked scripts, passed the preflight and was stashed away for good.

- auto_update.local_changes() is the one predicate both use:
  core.fileMode=false, porcelain -z, and plugins/ and plugin-repos/
  excluded by leading folder rather than substring (a core file under
  web_interface/static/v3/js/plugins/ now counts).
- Update Code's explicit stash leaves out both plugin folders; the
  pull's --autostash carries their edits and mode changes across and
  reapplies them.
- The automatic updater calls perform_core_update(stash_local_changes=
  False), which refuses instead of stashing edits that appeared after
  the preflight; update_core reports that as 'blocked'.

* fix(scripts): diagnostics follow the web autostart default and api_v3 package

#556 made a missing web_display_autostart mean "start" (only an explicit
false/off keeps the web interface down), but the diagnostics still said
otherwise: diagnose_web_ui.sh reported a missing key as "defaults to
false", diagnose_web_interface.sh said the web interface "will not start
unless this is set to true" and recommended enabling it, and
debug_web_manual.py printed False. Troubleshooting a down web UI pointed
users at a non-cause.

Both shell scripts now evaluate the setting with the launcher's own
autostart_enabled() (inline fallback if it cannot be imported) and report
on / off / not set (on) / unparseable config; debug_web_manual.py uses
the same function. They also check web_interface/blueprints/api_v3/
__init__.py: api_v3.py became a package in #553, so every healthy
checkout was reported as missing a file.

* docs(install): what install_service.sh installs; verify script port; no sudo for --help

install_service.sh installs and starts ledmatrix, ledmatrix-web and the
update-verify units, not only ledmatrix.service (systemd/README.md,
README.md). MIGRATION_GUIDE presented 'sudo install_service.sh --help'
as a harmless check; it now shows --help without sudo and warns what a
real run does. SSH_UNAVAILABLE_AFTER_INSTALL: verify_installation.sh
checks the web interface on port 5000.

* fix(display): size the preview after orientation and pixel mappers

display_geometry.physical_size claimed to give DisplayManager's answer but
only computed cols*chain x rows*parallel. RGBMatrix.width/height are measured
after the library's pixel mappers, so a Rotate:90 / orientation 90 chain
previewed 128x32 for a 32x128 panel and a U-mapper chain of four 256x32 for
128x64.

Model the built-in mappers' size effect as the pinned lib/pixel-mapper.cc
does (Rotate, U-mapper, V-mapper, StackToRow, Remap; Mirror and unknown
names leave it alone), and move the orientation composition here so
DisplayManager and the preview share it. The module docstring no longer
claims the sync handshake uses it; that imports only DEFAULT_CHAIN_LENGTH.

Audit finding F18.

The library answers several settings with a NULL matrix or abort() rather
than an error, so the display service crash-looped (Restart=on-failure)
instead of reaching fallback mode: rows above 64, chain_length above 255
(uint8_t binding setter, documented as "no upper limit"), a misspelled
hardware_mapping, and parallel 2-3 on a single-output mapping, reachable
from the Display form on the default adafruit-hat(-pwm) mapping. #586 only
guarded the Pi 5 subset.

- src/matrix_support.py holds the rules for every board (Options::Validate
  ranges, binding integer types, mapping names and outputs from
  lib/hardware-mapping.c) plus the Pi 5 ones, and is the one source of the
  API's numeric ranges.
- DisplayManager checks them before building options and raises
  MatrixSettingsRefused, so a hand-edited config falls back with a logged,
  reported reason. Emulator mode only warns.
- The config API refuses them with a 400 naming the setting; combinations
  are checked against stored values but reported only when the request
  sets a field involved.
- The hardware status file gains "cause" (settings/library/forced). The
  fallback log and Display banner give the Pi 5 rebuild hint only for a
  library failure instead of rebuild + gpio_slowdown advice for every
  failure; one Pi 5 slowdown recommendation (1-3, start at 1).
- The Display form offers classic/classic-pi1 and orientation 90/270 and
  renders any other stored mapping selected with a warning, so an
  unrelated save no longer rewrites them; the API accepts 90/270.

Audit findings F03, F16, F19, F21.

* docs(display): library limits, template defaults and Pi 5 slowdown

- rows 8-64, chain_length 1-255, parallel limited by the mapping's outputs,
  classic/classic-pi1 mappings and orientation 90/270 documented.
- Defaults are the config.template.json values: config migration adds
  missing keys from the template, so the listed "code defaults" never
  applied.
- One Raspberry Pi 5 gpio_slowdown recommendation: 1-3 in PIO mode,
  starting at 1.
- Troubleshooting describes the refused-settings fallback, and CHANGELOG
  corrects the Unreleased "no upper limit" entry.

* fix(scripts): scroll_speeds.py opens the panel with the service's options

--measure and --demo built RGBMatrixOptions from a private copy of the
display service's builder that had drifted: gpio_slowdown came from
display.hardware (default 2) instead of display.runtime (default 3), and
rp1_rio, panel_type, disable_hardware_pulsing, inverse_colors,
pixel_mapper_config and orientation were skipped, with different defaults
(hardware_mapping "regular", pwm_bits 11). A panel needing a high slowdown
was measured -- or garbled -- in a setup the service never drives.

The option filling in DisplayManager._setup_matrix moves, unchanged, into
DisplayManager.apply_matrix_options(options, config), which _setup_matrix
calls and the script reuses (overriding only limit_refresh_rate_hz for
--measure). The script now loads the whole config rather than the hardware
block. Tests pin the script's options to the service's attribute for
attribute.

* fix(scripts): scroll_speeds.py recommends keys the resolver honours

The ladder ended by telling users to set
display_options.scroll_pixels_per_second. scroll_config ranks that key
below the scroll_speed + scroll_delay pair, deliberately, and several
plugin schemas default the pair into config, so the advised key was
silently ignored (a schema-default 1/0.02 pair plus an advised 66 still
resolved to 50 px/s).

The advice is now the pair that selects the crisp speed exactly
(pixels_per_frame every frame_hold/refresh seconds), explains that the
pair outranks scroll_pixels_per_second, and gives the scoreboards'
per-league scroll_settings.scroll_speed (px/s) form. Tests resolve the
printed pair over a schema-default pair and check it lands on the
advertised speed and hold.

* docs: withdraw the target_fps claim for sports_scroll; fix the Vegas speed formula

- SPORTS_UNIFICATION.md still presented honouring global target_fps as
  sports_scroll's added behaviour and its one user-visible gain; note that
  it was withdrawn because it had become a speed multiplier.
- ADVANCED_FEATURES.md gave Vegas scrolling as
  (scroll_speed / target_fps) * elapsed; the real rule is scroll_speed px/s
  by elapsed time, through a 0.1-5 px per scroll_delay clamp when
  frame_based_scrolling is on.

* fix(dev): link-github links plugins from the ledmatrix-plugins monorepo

link-github <name> cloned https://github.com/ChuckBuilds/ledmatrix-<name>.git,
and those per-plugin repositories no longer exist: official plugins are
directories in the ledmatrix-plugins monorepo. It now clones (or pulls) the
monorepo once into the dev directory, finds plugins/<name>,
plugins/ledmatrix-<name> or the plugin whose manifest id is <name>, and
links it under its manifest id. With an explicit repo URL it still links a
single-repository plugin as before.

dev_plugins.json: github_user is honoured again (monorepo owner, e.g. a
fork), plus plugins_repo and plugins_branch; github_pattern, which was
documented but never read, is dropped and warned about. Ships
dev_plugins.json.example and git-ignores dev_plugins.json, both of which
the guide promised. Reading JSON falls back to python3 when jq is missing
(get_plugin_id silently returned nothing without jq).

update/status/list find the git checkout above a monorepo plugin
directory (its .git is not in the plugin dir), and update pulls a shared
checkout once. status no longer exits 1 when nothing is broken.

Docs: PLUGIN_DEVELOPMENT_GUIDE (quick start, link-github, configuration,
workflow, store integration, hello-world link, submission), and the
nonexistent scripts/git-hooks/pre-push-plugin-version and
scripts/bump_plugin_version.py replaced with the real rule: bump the
manifest version and run update_registry.py. scripts/dev/README.md and
CLAUDE.md updated to match.

* docs(scripts): monorepo workspace layout; fix_perms and install READMEs

MULTI_ROOT_WORKSPACE_SETUP described one sibling repository per plugin;
setup_plugin_repos.py links ../ledmatrix-plugins/plugins/* into
plugin-repos/ and update_plugin_repos.py pulls only the monorepo, and the
workspace file opens LEDMatrix plus ../ledmatrix-plugins.

scripts/fix_perms/README.md listed cache directories
fix_cache_permissions.sh never touches and a 'ledmatrix' service user
that doesn't exist (also in scripts/install/README.md); adds
safe_pip_install.sh. install/README: install_service.sh installs the web
and update-verify units too.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(update): keep the rollback's pip retries inside the unit time limit

The health check reinstalled the previous requirements by trying the
next bash path after any failure, including a 600 s pip timeout. Two
files, two paths: up to 40 minutes of pip alone, while systemd stops
ledmatrix-update-verify.service at TimeoutStartSec=30min -- killing the
rollback half-way and leaving the update 'verifying' until the web UI
calls it lost.

- Like permission_utils.install_requirements_file, only a sudo refusal
  moves on to the next bash; a pip that ran and failed or timed out is
  not repeated. The refusal wording is one list
  (permission_utils.SUDO_REFUSAL_PHRASES), mirrored in the stdlib-only
  verifier and pinned equal by a test.
- All reinstalls in one rollback share a 600 s budget.
- WORST_CASE_SECONDS adds up every timeout on the longest path (27.5
  min); a test holds it under the unit's TimeoutStartSec and that under
  the web UI's VERIFY_LOST_SECONDS.

* fix(plugins): prepare plugin configs one way for load, saves, GET, hot reload and dev tools

Plugin config was prepared differently depending on how it arrived:

- JSON POST /plugins/config built a partial body on schema defaults, so
  {"enabled": true} reset every other setting of the plugin. It now merges
  onto the stored section first, as the form path already did.
- Legacy-boolean normalization (#588) ran only at load: GET /plugins/config
  returned the raw boolean, posting it back failed validation, and hot
  reload handed plugins the raw section (a legacy dynamic_duration: true
  came back as a boolean). schema_manager.prepare_plugin_config (normalize,
  then defaults) is now used by PluginManager.load_plugin, both save paths,
  GET, the save notifications and DisplayController's hot-reload callback.
- The JSON save's filter kept only enabled/display_duration/live_priority
  and dropped a submitted skin, skin_options or vegas_* tuning key. There
  is now one core-owned per-plugin list, schema_manager.CORE_PLUGIN_PROPERTIES,
  used by validation and by the save filter; PluginManager's
  CORE_OWNED_CONFIG_KEYS is its vegas subset.
- Plugin sections posted to /config/main were stored verbatim, including
  values /plugins/config rejects. They now go through the same preparation
  (_prepare_plugin_config_for_save, extracted from save_plugin_config), and
  a failing section rejects the whole save before anything is written.
- dev_server read only top-level defaults and let a schema enabled:false
  win; build_full_config shallow-merged overrides, dropping sibling
  defaults; the harness extracted defaults differently from the device.
  loading.build_config now uses the device's extraction and preparation,
  and dev_server, check_plugin, render_plugin and the harness all use it.

installer_chmod saw no mode change left to check. The updater was fine:
with the upstream commit at 100755 the --autostash carries the device's
chmod across. Verified under Linux (WSL, git 2.43): the old helper fails
exactly as CI did, the fixed one passes all 63 tests in the file.

ChuckandClaude Opus 5 92ac231138 fix(fonts): load 4x6 on its pixel grid, from any working directory (#565) 
* fix(fonts): load 4x6 on its pixel grid, from any working directory

`extra_small_font` loaded 4x6-font.ttf at 6, off the face's 7px grid.
Under `draw.fontmode = "1"` the mono rasteriser thresholds each glyph at
50% coverage, so every glyph lost its fourth column and deformed:
christmas-countdown rendered "UNTIL" as "VM1JL". The advance is 5px at
both sizes, so snapping to 7 reflows nothing.

- Sizes in DisplayManager._load_fonts go through crisp_size() instead of
  literals. crisp_size / FONT_PIXEL_GRID / FONT_NAME_ALIASES move to
  src/common/font_layout.py; sports_card re-exports them.
- Mirror the fix in VisualTestDisplayManager, the harness's fork of
  _load_fonts. Without it every golden is blessed at the old size.
- Resolve bundled font paths against the install root, not the cwd.
  FontManager._resolve_asset_path now delegates to
  font_layout.resolve_asset_path (kept by name; plugins probe for it).
- The startup banner's middle rung snaps to 7; the 5 rung stays off-grid
  on purpose (the only size that fits a dotted quad on 64px).
- loading.py reads all plugin JSON as UTF-8 (cp1252 on Windows aborted
  check_plugin.py on a 0x9d byte).
- check_plugin.py reports in ASCII and never dies on an unencodable char.

* fix(fonts): resolve relative asset paths from the install root, not the cwd

resolve_asset_path checked os.path.exists(relative_path) unconditionally,
so a relative asset path was still resolved against the process cwd first
-- exactly the dependency this module exists to remove. An unrelated
working directory that happens to contain assets/fonts/4x6-font.ttf (a
stale checkout, a copied assets folder, another project) would shadow the
real bundled font instead of the install root ever being consulted.

Only an absolute path is now returned as-is; a relative path always
resolves against _INSTALL_ROOT first, matching the docstring's stated
contract. FontManager._resolve_asset_path delegates to this function, so
it's covered by the same fix.

ChuckandClaude Opus 5 968b953a51 fix(display): pin one text layout engine, and give the 5x7 BDF face a size (#539) 
* fix(display): pin one text layout engine, and give the 5x7 face a size

Two ways a font could render differently on two machines running the same
code, both found while diagnosing four plugins whose golden images passed on
the machine that generated them and failed everywhere else.

**Layout engine.** `ImageFont.truetype` picks its engine at load time: Raqm
where the host Pillow was built with libraqm, Basic otherwise. The two round
fractional glyph advances differently. `PressStart2P-Regular.ttf` at 8px has
whole-pixel advances, so they agree — which is why most of the fleet matched
everywhere and hid this. `4x6-font.ttf` at 6px does not: glyph positions drift
cumulatively along a run, and the four plugins that draw body text in it
(geochron, of-the-day, christmas-countdown, ledmatrix-weather's almanac) are
exactly the four whose goldens travelled badly.

Every core font load now goes through `src/common/font_layout.load_truetype`,
which pins the Basic engine, so a render depends on the font file and the size
and nothing else. Basic gives up complex-script shaping and kerning pairs;
neither applies to bitmap-grid faces on an LED panel. Output is unchanged on a
host without libraqm.

**Zero font height.** `DisplayManager` built the 5x7 BDF face with
`freetype.Face(path)` and never called `set_char_size`, so `face.size.height`
stayed 0 and `get_font_height()` returned 0 for it — callers stacking rows by
`prev_y + prev_height + gap` drew two lines on top of each other. The
start-up line `Calendar font size: 0 pixels` has been printing the symptom all
along. `font_manager._load_bdf_font` already called `set_char_size`, so
whether measurement worked depended on which path loaded the face.

`DisplayManager` now sets it too, and `get_font_height()` falls back to the
strike the file declares rather than returning a zero line height.

* fix(display): give the startup banner a rung that fits a full address at 64px

CI caught what pinning the layout engine exposed rather than caused.
`_fitting_font` walks PressStart2P then 4x6 at 6px, and "255.255.255.255" --
the widest thing the startup banner ever shows -- measures 66px at 4x6/6px
against the 62 a 64x32 panel has to give. It used to squeak in only because
the measurement depended on which layout engine the host Pillow happened to
have; with the engine pinned it does not, so the rung the worst case actually
needs is now in the ladder instead of implied: 4x6 at 5px, which measures 51.

The fallback was wrong in the same place. When nothing in the ladder fit, it
returned `self.font` -- the *widest* option, and precisely how "Initializing"
came to run off the side of a 64px panel to begin with. It returns the
narrowest face that loaded now.

test/test_initializing_screen.py: 34 passed.

* fix(display): name the exceptions the BDF strike read can raise

Codacy flagged the try/except/pass. It was already narrow in intent -- a
malformed strike table on the measurement path must degrade to "size unknown"
rather than take the display down -- but a bare `except Exception: pass` says
neither of those things and hides a genuinely broken font behind a silent 8px
fallback. It now catches what reading `available_sizes` can actually raise and
logs which face failed.

ChuckandClaude Opus 5 d12323e7f1 perf(scroll): pace frames to the panel — 44→100 fps, stalls 14% → 0.02% (#523) 
* perf(scroll): pace frames to the panel, not to a fixed sleep

Scrolling ran at 44-46 fps on a 2x128x64 chain and 14-17% of frames took
41-53ms, which reads as judder. Four independent causes, each measured on
the hardware; details and the diagnostic recipe are in
docs/SCROLL_PERFORMANCE.md.

The high-FPS loop slept a flat 8ms after every render. display() has
already blocked on the panel's vsync by then, so that sleep was added to a
wait that had happened: ~4ms of render plus 8ms put each iteration at ~12ms
against a 10ms refresh grid, so every swap missed a refresh and the loop
settled at 50fps while asking for 125 -- with no headroom, so a further
14% of frames slipped again. It now sleeps only the remainder, with a 1ms
floor so plugin threads still get the GIL.

ScrollHelper stepped position on a wall clock at 1/scroll_delay steps per
second. Plugins set scroll_delay to the frame period, so that comparison
sat exactly on its own threshold: a frame arriving a hair early moved zero
pixels and rendered an identical frame, dirty-tracking skipped the swap, it
returned in ~2ms, and the beat repeated. No scroll_delay value tunes that
out -- a shorter delay trades stalled frames for periodic double-steps.
Both modes now accumulate elapsed time at the same configured speed, so
position stays proportional to real time.

Sub-pixel blending goes back to off by default. It renders a half-step by
mixing two adjacent columns, which on a coarse panel showing pixel-font
text alternates crisp and smeared frames and reads as shimmer -- visibly
worse than integer stepping on the hardware. Vegas mode still opts in.

disk_cache uses orjson when importable, falling back to the stdlib. Encoding
a ~1MB record drops from 14.8ms to 5.4ms end-to-end, and that work holds the
GIL while a marquee is on screen. display_manager also checksummed the whole
framebuffer twice per frame (dirty tracking, then the preview snapshot); the
snapshot now takes the checksum the caller already computed.

New src/common/scroll_config.py resolves scroll settings in one place. Five
ticker plugins each hand-rolled this and disagreed: odds-ticker ranked the
deprecated scroll_pixels_per_second above the documented scroll_speed/delay
pair, and because that key carries a schema default the documented settings
were dead for every user (ChuckBuilds/ledmatrix-plugins#408), while
ledmatrix-leaderboard read the same key only as a fallback. The resolver also
warns when a speed will not advance a whole number of pixels per refresh,
which is the property that actually determines whether a scroll looks smooth.

scripts/build_rgbmatrix_nogil.sh rebuilds the rgbmatrix binding so it
releases the GIL. Upstream declares SwapOnVSync without nogil, unlike
SetPixel/Clear/Fill beside it, so the render thread held the GIL for the
whole vsync wait and starved background threads into long uninterruptible
bursts. The script patches, builds and self-verifies into a scratch tree;
--install backs up the original and rolls back if the service does not come
back healthy.

Measured after: 100 fps locked, no stalls observed, render thread down from
51% to 19% of one core.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(display): keep the panel swap locked to vsync while scrolling

Dirty tracking skipped SwapOnVSync for byte-identical frames. That is the
right call for static content, but SwapOnVSync is also what paces the render
loop, so skipping it skips the wait for the panel: a duplicate frame returns
in ~8ms instead of ~10ms on a 100Hz panel, advances the strip only 0.8px
instead of 1.0px, and so makes the next frame more likely to repeat as well.
The effect sustains itself once it starts.

Measured over 20 minutes on a 2x128x64 chain, both scrollers configured
identically at 100 px/s:

    leaderboard   10ms x35, 11ms x3            (clean)
    odds-ticker   10ms x26, 8ms x7, 15ms x5    (~20% duplicates mid-scroll)

The duplicates were not end-of-cycle idling -- 38% of fast frames fell within
90s of a scroll completion against 35% of normal frames, a null result. The
trigger is per-frame work: odds does more of it, and more variably, so it is
first to land a frame that advances less than a whole pixel.

Pushing an identical frame costs one canvas copy. Falling out of vsync lock
costs smooth motion. Static content is untouched, because
is_currently_scrolling() expires on its own inactivity threshold -- covered
by test_stale_scrolling_state_stops_forcing_pushes so a plugin that stops
scrolling without saying so cannot pin the panel into always-push.

Also de-flakes test_snapshot_still_written_on_skip, which asserted a strict
mtime increase between two writes that can land in the same filesystem tick;
it failed about two runs in three on Windows regardless of the code under
test. The file is now backdated before the check.

156 tests pass on the Pi. Not yet confirmed by eye on the panel.

* fix(scroll): report the frame-time tail, and stop the row-major blit

Two problems, both found by looking at the panel rather than the metric.

The frame-stats line reported ONE instantaneous frame every 5 seconds --
about 1 frame in 500 -- printed beside a 100-frame average. Both hide exactly
the fault they are used to chase: a 2ms duplicate and a 21ms double-wait
average to precisely 10ms, so a ticker stalling on half its frames still
reports a healthy "Avg FPS: 100.0". That reading cost several rounds of
chasing the wrong layer. The line now aggregates every frame since the last
log and reports median, p95, max, min, and explicit stall and skip rates
(past 1.5x the median missed a refresh; under half never reached the panel,
because dirty tracking skipped the swap so the frame never waited on vsync).

On the hardware this now reads:

    leaderboard  100.0 fps over 501 frames | median 10.00ms p95 10.05ms
                 max 10.34ms | stalls 0 (0.0%) skips 0 (0.0%)

The binding rebuild's blit patch becomes opt-in (RGB_PATCH_BLIT=1, default
off). Reordering that loop to row-major changes what a torn frame looks like:
column-major tearing shows as a vertical seam, row-major as a horizontal split
between the panel's upper and lower halves. On a 1/32 scan panel that reads as
a one-pixel fold across the middle of every panel, which is what was reported
on hardware and what went away when the blit was reverted. All of the measured
gain comes from the SwapOnVSync change, so the risky half is simply not worth
taking; the header says so.

Also fixes --install resolving its paths against $HOME, which is /root under
sudo, so it looked in /root/rgbmatrix-nogil-build and died with "no built
module found" on a machine where the build had just succeeded. It now resolves
SUDO_USER's home. Both build paths are verified on the Pi: default yields one
GIL-release site, RGB_PATCH_BLIT=1 yields two.

* feat(scroll): let users pick a crisp speed for their own panel

Whole-pixel motion was previously only available at multiples of the refresh
rate -- 100, 200, 300 px/s on a 100Hz panel. 100 px/s crosses a 256px panel in
2.6s, which is brisk for reading, and everything slower had to blend (blur) or
repeat frames unevenly (judder). There was no way to ask for 50 px/s and get
clean motion.

SwapOnVSync takes a framerate_fraction the display manager never passed. It
holds each frame for N panel refreshes; the panel keeps refreshing at its full
rate throughout, so holding costs nothing in flicker and only changes how often
a NEW image is presented. That turns 50 px/s into one whole pixel every second
refresh instead of half a pixel every refresh.

The crisp speeds are therefore refresh_hz / hold * pixels_per_frame, and that
ladder depends on the panel: a Pi Zero on a long chain has a different set of
good speeds from a Pi 4 on a short one. crisp_ladder() enumerates them and
solve_crisp() picks the best match for a requested speed.

solve_crisp weights motion quality rather than picking the numerically nearest
entry, which matters more than it sounds. Asked for 30 px/s, nearest-by-value
answers 28.6 -- 2px jumps at 14fps -- over 33.3, which is single-pixel motion
at 33fps and obviously better on the panel. The target is also clamped into the
ladder's range first, because relative error saturates near 1.0 for a target
far outside it and the quality penalty would otherwise answer "10000 px/s" with
the slowest entry.

configure() snaps to the ladder and applies the hold when given a display
manager. Without one the hold silently cannot happen and motion falls back to
fractional pixels, so it warns rather than failing quietly. set_frame_hold()
resets to 1 when scrolling stops, so one plugin's pacing cannot leak into
whatever is on screen next.

scripts/scroll_speeds.py is the user-facing part: it prints the ladder for the
configured rate, measures what the panel ACTUALLY manages (--measure, for
hardware that cannot reach its configured limit), highlights the nearest option
to a wanted speed, and demos one live. It never starts or stops the display
service itself -- doing that inside a script stranded the panel twice today.

Speeds below ~20 px/s remain stepped regardless. That is the pixel pitch, not a
software limit.

Also fixes the dirty-tracking test spy, which stubbed SwapOnVSync with a
single-argument function and would have masked the new call as a failed push,
and rewrites a configure() test that had started passing for the wrong reason:
it asserted a judder warning, which snapping now prevents, and was matching the
unrelated "hold could not be applied" warning instead.

183 tests pass on the Pi.

* fix(scroll): tie the frame hold to the scroll, not the plugin

The hold applied in configure() never reached the panel. Plugins share one
display manager, and set_scrolling_state(False) -- fired whenever ANY other
plugin finishes its scroll -- reset the hold to 1. A hold set once at plugin
construction was therefore always gone by the time that plugin rendered.

The symptom was a log line that lied. ledmatrix-stocks reported

    Scroll configured: 50.0 px/s (1px every 2 refreshes = 50.0 fps, smooth)

while the panel measured 100.0 fps, median 10.00ms. Config, resolution and
snapping were all correct; only the pacing silently was not applied.

set_scrolling_state(is_scrolling, frame_hold=1) now carries it, so the hold
lives exactly as long as the scroll that asked for it. configure() reports the
value as ScrollSettings.frame_hold instead of applying it -- applying it behind
the caller's back could never have been right on a shared display manager.
Existing callers are unaffected; the default keeps one frame per refresh.

Verified on hardware: stocks at 50 px/s now measures

    50.0 fps over 251 frames | median 20.00ms p95 20.09ms | stalls 0 skips 0

20.00ms being exactly two refreshes, with the panel still refreshing at 100Hz
underneath so flicker is unchanged.

test_another_plugin_stopping_does_not_strand_a_hold pins the interaction that
broke this.

* fix(scroll,cache): resolve CodeRabbit review on #523

Eight findings, all reproduced before fixing.

scroll_config.configure() read the refresh rate *after* resolve() had
already used it. resolve() fills in target_fps, pixels_per_frame and the
judder warning from that rate, so on a 60Hz panel every one of them
described 100Hz -- and with snap_to_crisp=False nothing downstream
corrected it, so set_target_fps() paced the helper to 100 FPS. The rate
is now settled first, and falls back to the global config rather than
straight to the default.

refresh_hz_from_config() used `(cfg.get("display") or {}).get(...)`,
which raises AttributeError when either level is truthy but not a
mapping -- out of a function whose whole contract is a rate or a default.

The frame-stats line reported the upper-middle sample as the median and
the 96th sorted sample as p95 of 100. Both are also thresholds (stalls
at 1.5x the median, skips at 0.5x), so the counts were biased too. The
arithmetic is now in frame_stats()/format_frame_stats(), testable
without a clock.

configure()'s docstring and docs/SCROLL_PERFORMANCE.md still said it
applies the frame hold and warns when it cannot. It deliberately does
neither since "tie the frame hold to the scroll, not the plugin"; a
caller following the old text would omit set_scrolling_state() and slow
snapped speeds would still present every refresh.

disk_cache had no policy for non-finite floats: orjson writes null,
the stdlib writes NaN/Infinity, and orjson then rejects those legacy
files so DiskCache.get deleted them as corrupt. One behaviour on both
paths now -- write null, keep legacy records readable. allow_nan=False
detects the values; the replacement walk runs only when there is one,
so the ordinary write path is byte-identical and pays nothing.

build_rgbmatrix_nogil.sh picked the build artifact with a glob piped to
`head -1`, which sorts cpython-311 ahead of cpython-313, so a stale .so
staged in from the source tree was installed as core.so while the GIL
check -- which reads the generated core.cpp, not the .so -- still passed.
It now requires the current interpreter's exact ABI name and fails
closed. Its systemctl calls were also unchecked under `set -uo pipefail`:
a failed stop left the old service running, the following start
succeeded as a no-op, and the health check reported SUCCESS for a
binding that was never loaded.

orjson floor raised to 3.11.6 for CVE-2025-67221 (unbounded recursion
in dumps); it covers the project's Python 3.10-3.13 range.

Adds test/test_cache_nonfinite_floats.py (14) plus regression tests in
test_scroll_config.py and test_scroll_helper.py. 9 of the cache tests
and 9 of the scroll_config tests fail against the pre-fix code.

* test(harness): keep the visual double's signature tied to production

Moves set_scrolling_state's frame_hold into the test double here, where
DisplayManager gains it, rather than in #534 where it arrived a PR early.
CodeRabbit flagged the #534 version correctly: a double that accepts an
argument production does not lets the call pass every harness run and
raise TypeError on the panel, which is the one failure a safety harness
exists to prevent.

The drift has now gone both ways across two branches -- double behind
production on this branch, double ahead of it on #534 -- so it is pinned
instead of remembered. test_display_double_parity.py compares the two
signatures and fails with the direction of the drift named. It reads the
files with ast rather than importing them, because display_manager
imports rgbmatrix at module scope and this check should hold on a laptop
and in CI as well as on a Pi.

Plugins begin passing frame_hold in ledmatrix-plugins#462, which is why
production and the double both need it before that lands.

Full suite: 3889 passed.

ChuckandClaude Opus 5 a0d3e64099 fix: ten defects found validating the whole plugin fleet on hardware (#534) 
* fix(core): register tom_thumb, accept frame_hold in the test double, wire api_v3's managers

Three independent fixes found while validating every plugin on a 256x64 rig.

FontManager never registered tom_thumb even though assets/fonts/tom-thumb.bdf
ships with the core, so every plugin offering it logged "Font family
'tom_thumb' not found" (16 warnings per countdown render) and had to carry a
private loader to use a bundled font. Closes #524.

VisualTestDisplayManager.set_scrolling_state() lacked the frame_hold parameter
that DisplayManager gained, so any plugin passing it died with TypeError at
render time and failed every size. Nine plugins now make that call;
ledmatrix-stocks and ledmatrix-leaderboard were failing outright and the other
seven only passed because their scroll path was unreachable without data.
Closes #525.

api_v3 declared module-level config_manager/plugin_manager = None that nothing
ever assigned -- app.py sets the blueprint attributes, which the other 150+
call sites use. Three sites read the decoys, so /health reported the config
unreadable and the plugin system uninitialised (making "degraded" permanent and
unreachable-by-design) and /display/current fell back to a hardcoded 128x64 on
every rig. The decoys are removed rather than assigned, so a bare name is now a
NameError at test time instead of a silent None. The same function's first-call
uptime was computed from two separate clock reads and came out negative.
Closes #529.

Verified on the rig: both previously-failing plugins render, the tom_thumb
warnings are gone, /health reports "healthy" with all three checks passing, and
/display/current reports the real 256x64.

* fix(core): unique snapshot temp name, honour on-demand requests, skip empty starlark

The preview snapshot wrote through a fixed "<snapshot>.tmp". /tmp is
world-writable and sticky, and the display service runs as a different user
from the tooling, so a leftover temp owned by anyone else became unopenable
even by root -- fs.protected_regular refuses O_CREAT on a foreign file in a
sticky directory. The preview and the health check's liveness proxy then froze
until someone deleted the file by hand; on the test rig that meant 23 hours of
a healthy display reporting "hardware: stale". Now uses tempfile.mkstemp with
cleanup on failure, matching the hardware-status write a few hundred lines
above. Closes #528.

_poll_on_demand_requests read its mailbox with max_age=3600, and get() defaults
the in-memory TTL to max_age -- so the first request was pinned in memory for an
hour and every later poll returned that stale copy. No second on-demand request
was honoured until the service restarted, while the API kept returning 200.
get() already documents memory_ttl=0 for exactly this cross-process case.
The consumed request is also now deleted: leaving it on disk meant a restart
replayed the previous request, activated it, and ignored the one the caller had
just made. Closes #530.

starlark-apps returned None from display() when it has no app to show, which is
the state of every install without Pixlet and of a fresh one before any app is
added. The controller only skips on a boolean False, so that held a black panel
for the full display_duration instead of rotating on. Closes #456 (core side).

Verified on the rig: two consecutive on-demand requests with no restart between
them are both activated, where the second was previously dropped in silence.

* perf(harness): share one cache across a plugin's renders

_instantiate built a fresh MockCacheManager for every (size, mode), and that
mock is a per-instance in-memory dict, so each render was a cold start. A plugin
that fetches per game or per player re-fetched everything N times over --
baseball-scoreboard at one size took 840s for nine renders where the arithmetic
said ~72s, and at eight sizes it exceeded a 900s timeout.

The second and later renders also never exercised the cache-hit path, which is
what a running rig executes almost all of the time, so a caching regression
could not be caught here.

The cache is now built once per render_plugin_matrix call and threaded down.
The display manager stays per-render -- the bounds checking depends on that --
so only fetched data is shared.

Measured on the rig, same render counts and same goldens:
  tide-display         2s -> 1s   (32 renders)
  cricket-scoreboard  10s -> 3s   (24 renders)
No pass/fail change across tide-display, cricket-scoreboard, clock-simple,
geochron, christmas-countdown, of-the-day, web-ui-info and incoming-packages.

Closes #533.

* fix(scripts): run standalone plugin tests instead of collecting nothing

run_plugin_tests.py discovered every plugin test file and handed the lot to
pytest. Most plugin tests are standalone scripts -- module-level main() plus an
`if __name__ == "__main__"` guard, signalling through an exit code -- and pytest
collects zero items from those. The run printed how many files it had *found*,
then "no tests ran", and exited without executing any of them. On a rig with all
44 first-party plugins that is 151 of 248 files.

Files are now classified and each kind runs under the right runner: pytest for
real test modules, subprocess for scripts, honouring the 0 pass / 2 skip / 1
fail convention ledmatrix-plugins' own runner established (a script that wants a
tty or an LED matrix is a skip, not a regression).

Before:
    $ python3 scripts/run_plugin_tests.py -p countdown -d ~/LEDMatrix/plugin-repos
    Found 1 test file(s)
    collected 0 items
    no tests ran in 0.31s                      rc=0

After:
    Found 1 test file(s) -- 0 collectable, 1 standalone script(s)
    1 passed, 0 skipped, 0 failed (scripts)    rc=0

Verified across three shapes: countdown (1 script), jellyfin-now-playing and
pomodoro-timer (pytest only, 16 and 42 tests), and ledmatrix-flights (11 files
split 4 collectable / 7 scripts, all seven of which had never run).

Closes #532.

Running the flights scripts for the first time also surfaced four genuinely
failing tests there, hidden by the mirror-image bug in the plugins repo's own
runner -- filed as ChuckBuilds/ledmatrix-plugins#464 and #465.

* fix(harness): give an empty-looking mode a few frames before warning about it

check_plugin's "drew nothing but display() returned X" warning fired on a single
frame, rendered with force_clear=True, under a frozen clock. All three defeat a
scrolling plugin, whose first frame is legitimately its blank scroll-in buffer.
Across 44 first-party plugins, 60 of 76 warnings were false -- the rate at which
people stop reading a warning, which matters because the true positives are
real: a mode that draws nothing and does not return False holds a blank panel
for its whole display duration.

An apparently-empty frame is now re-driven for up to 48 more frames with
force_clear=False (force_clear means "reset the scroll", so repeating it would
redraw frame 1 for ever) and with the clock advancing -- freezegun's factory
where time is frozen, a real sleep where it is not, since scroll position is
usually a function of elapsed time. The first frame that draws content replaces
the result.

The clock is moved back afterwards. It is shared by every render in the matrix,
so time borrowed by the probe leaked into later modes and drifted their goldens
-- f1_upcoming picked up 5 spurious drifts before this was restored.

Measured on the rig:

                        empty warns          check
                        before  after
  f1-scoreboard            42      0    48 PASS / 0 FAIL, goldens intact
  ledmatrix-elections      16      0    16 PASS / 0 FAIL
  on-air                    8      8    true positive, kept
  nfl-draft                 8      8    true positive, kept
  clock-simple/geochron/    0      0    unchanged
  christmas-countdown

58 false positives gone, both true positives kept, no golden regressions. Cost
is confined to modes that really are blank: plugins that draw immediately are
unchanged (clock-simple and tide-display still 2s), while on-air -- eight
deliberately blank modes -- goes to 21s.

Closes #527.

* fix(harness): load nested schema defaults, and merge caller config at leaf level

load_config_defaults read only top-level properties. An object property carries
its defaults on its children, not on itself, so everything nested was dropped --
2,386 defaults across 37 of 44 plugins, soccer-scoreboard alone losing 539 of
565. render_plugin_matrix's comment says the plugin then "behaves like a real
install", which for most of the fleet it did not.

_defaults_from_properties now recurses. merge_config deep-merges the caller's
config onto the result so an override lands at the leaf: a shallow merge would
let -c '{"nhl": {"enabled": true}}' replace the whole nhl subtree and discard
every other nhl default, which is the same class of bug being fixed here.

Measured before/after across all 49 installed plugins on the rig: **no render
changed** -- identical PASS/FAIL counts, byte-identical output, goldens intact.
Plugins already fall back to the same values internally via config.get(key,
default), so supplying them explicitly agrees with what they were doing. The
defaults really are arriving now:

  ufc-scoreboard        9 -> 87 defaults
  ledmatrix-flights    51 -> 95
  masters-tournament   10 -> 51
  cricket-scoreboard   22 -> 50
  tide-display         12 -> 18

and hockey-scoreboard, which used to load nhl.enabled=None, now gets
nhl.enabled=True with its full display_modes block.

Caveat worth carrying: the eight plugins with the most nested config
(soccer, baseball, basketball, hockey, lacrosse, football, afl, nrl -- 1,634 of
the 2,386 dropped defaults, 68%) could not be measured. They import
src.common.sports_shared, which the test rig's core branch predates, so they
fail to load there identically before and after. Re-run this comparison against
a core that has that module before trusting the "nothing changed" result for
them; those are exactly the plugins whose renders should change most.

Closes #531.

* refactor: narrow the exception handlers this branch introduced

Codacy flagged the new code; it passes on other recent PRs, so the finding is
mine. Four of the five broad `except Exception` clauses I added were catching
far more than they needed to, which is the same shape as several bugs this
branch fixes -- hello-world's TypeError sat invisible for exactly this reason.

  freezer() / move_to() / tick()   -> (AttributeError, TypeError, ValueError)
  cache_manager.delete()           -> (OSError, AttributeError, KeyError)

The fifth stays broad and now says why: it wraps a call into a plugin's own
display(), which can raise anything, and the first frame has already rendered --
so a failure there must not turn a good result into an error.

Verified against a checkout of main: f1-scoreboard 48 PASS / 0 FAIL with 0 empty
warnings, on-air keeps its 8 true positives, clock-simple 8 PASS. geochron shows
7 golden drifts both before and after this branch, so it is not from these
changes -- its committed goldens predate #521's 1-bit text rendering.

* fix: resolve CodeRabbit review and Codacy findings on #534

CodeRabbit raised six; all six were real.

The test double had drifted ahead of production. VisualTestDisplayManager
accepted set_scrolling_state(frame_hold=...) while DisplayManager did not,
so such a call passed every harness run and would raise TypeError on the
panel -- the one failure a safety harness exists to prevent. frame_hold
belongs to the change that adds it to DisplayManager (#523), so it moves
there and the double matches main again.

The harness swallowed exceptions from re-rendered frames. _settle_loop
re-renders a mode that came back blank, to give a scroll time to draw;
returning silently on a crash meant a mode that renders one good frame
and then explodes was reported as passing. Recorded on result.error now,
keeping the captured frame so the failure stays inspectable.

starlark-apps display() returned True after _display_frame() failed, so
the controller held a dead frame for the whole display_duration instead
of rotating on. _display_frame now returns bool on all three paths.

run_plugin_tests.py used env.setdefault for PYTHONPATH and
LEDMATRIX_CORE, so an inherited value won and the subprocess imported a
different core than the one under test -- ledmatrix-plugins#467 exactly.
Prepends PROJECT_ROOT and sets LEDMATRIX_CORE unconditionally.

The on-demand mailbox is polled after every frame, ~125x/second on a
scrolling mode, and the read is deliberately uncached, so it was that
many disk reads per second to find nothing. Floored at 250ms, which is
imperceptible for a web-UI click. Consuming it also deleted whatever was
present rather than what had just been processed, so a request posted
while the previous one was in flight was thrown away and never ran; the
delete is now keyed by request_id. That narrows the window rather than
closing it -- a true atomic claim needs a primitive the cache layer does
not offer, and the code says so rather than implying otherwise.

Codacy's 2 criticals were bandit B404/B603 on the subprocess call added
to run_plugin_tests.py. Fixed interpreter, argument list, no shell;
annotated with the repo's existing nosec convention. Bandit is clean on
the file.

Adds test/test_on_demand_mailbox.py (8), test_starlark_display_contract.py
(4) and two settle cases in test_harness_empty_claimed.py. 4, 4 and 2 of
those fail against the pre-fix code. Full suite: 3961 passed.

* chore: satisfy Codacy's subprocess checks on the new test runner

Codacy runs Bandit and Opengrep (its Semgrep fork). The new
subprocess.run in scripts/run_plugin_tests.py trips three patterns, on
two different lines:

  Bandit   B404 on the import, B603 on the call
  Opengrep dangerous-subprocess-use-audit          on the run( line
           dangerous-subprocess-use-tainted-env-args on the argv line

A nosemgrep applies only to its own line, so the call line and the argv
line each need one; a single comment on the call covered neither rule
fully. Suppression is the right answer here rather than a rewrite: the
interpreter is sys.executable, the arguments are a list, and no shell is
involved, so there is nothing to word-split or expand.

Matches the pair the rest of the repo already uses for this shape --
permission_utils.py, plugin_loader.py, install_dependencies_apt.py.

Codacy: 0 new issues, up to standards.

* chore: leave visual_display_manager untouched so #523 can merge

The only change this branch made to that file was a docstring, and it
collided with #523's rewrite of the same method -- so #534 and #523 each
merged cleanly against main but conflicted with each other. Reverted to
main's text; #523 owns this method and adds frame_hold to it.

The note the docstring carried ('frame_hold arrives in #523') would have
been stale the moment #523 landed anyway. The parity test in #523 is
what actually keeps the two signatures honest.

* chore: add the Ruff suppression nosec/nosemgrep do not cover

Ruff reports S603 on the same call Bandit and Opengrep do, and none of
the three suppressions covers the others. Confirmed the precondition
first: path comes from discover_plugin_tests(), which globs test files
inside the repo, and the call is a fixed interpreter with a list argv
and no shell.

ChuckandClaude Opus 5 91d15a8943 fix(display): draw text 1-bit, so glyphs stay crisp on the LED grid (#521) 
An LED panel has no partial brightness. PIL defaults ImageDraw's fontmode to
"L", which anti-aliases TrueType glyphs into a grey fringe the panel can only
round off -- a 4px glyph arrives smeared into 3px.

DisplayManager creates its shared `draw` in six places and set fontmode at
none of them, while _load_fonts loads extra_small_font as 4x6-font.ttf at
size 6. Measured at draw time, that face at that size puts 74% of its lit
pixels at partial coverage. Every plugin drawing small text through the
shared draw inherited the blur; geochron was the case that surfaced it.

The harness's VisualDisplayManager had the same gap, which mattered more than
it looks: goldens were recording anti-aliased text that production would not
produce, so the harness could not have caught this. Fixing only production
left geochron still blurry under the harness -- that is how the second site
was found.

Both are set to "1" so the harness renders what the panel renders.

ChuckandClaude Opus 5 f887063434 test(harness): flag a mode that draws nothing without reporting it (#447) 
The controller skips a mode whose display() returns False and treats
anything else -- including None -- as "content was shown". A mode that
draws nothing and does not return False is therefore never skipped, and
because a mode switch clears the panel first, it sits on a blank screen
for its whole display duration. Two sports plugins shipped exactly that.

The harness rendered those modes and passed them, because it called
display() and discarded the result. Capture it, and warn when a render
produced no lit pixels while claiming content.

Warn-only by default, and deliberately so: a scroll mode's first frame
is legitimately its blank scroll-in buffer, which is 42 of these on the
F1 scoreboard alone. Plugins whose modes are known to draw on their
fixture data can opt into failing via harness.json {"empty_check":
"strict"}, matching how the fill check is staged.

Worth being clear about the limit: this only sees what the fixtures
render. It would not have caught the sports bug, whose fixture seeds
games so the empty path never renders -- that needs the source-level
gate in the plugins repo. What it does catch is the same mistake in any
plugin whose empty state the harness does happen to reach, which is
coverage there was none of before.

* fix(web): implement delete_cached so the font catalog cache actually invalidates

api_v3.py's font upload/delete handlers import delete_cached from
web_interface.cache, but the function was never defined. The surrounding
except ImportError silently swallowed the failure, so the fonts_catalog
cache entry survived uploads/deletes and newly uploaded fonts did not
appear until the TTL expired or the service restarted.

* fix(web): remove dead weather/stocks partial routes that returned 500

The partial dispatcher still routed 'weather' and 'stocks' to loaders
rendering v3/partials/weather.html and stocks.html — templates that no
longer exist since weather and stocks became store plugins. Requesting
either partial raised TemplateNotFound, which the catch-all turned into
a 500. No template or JS references these partials (the only 'weather'
hit in the front end is a plugin-store category filter option), so the

* fix(deps): align contradictory psutil/Flask-Limiter/freetype-py pins

requirements.txt's optional-install comment recommended psutil>=5.9,<6.0
while web_interface/requirements.txt hard-requires >=6.0,<7.0 — anyone
following the comment ends up with an unsatisfiable pair. The comment now
recommends the same range the web interface requires (all psutil APIs
used — Process, boot_time, cpu_percent, disk_usage, virtual_memory — are
stable in 6.x). Flask-Limiter gains the same <4.0 cap in both files and
freetype-py the same >=2.5.1 floor.

* fix(config): add template keys the code already reads

display.hardware gains pixel_mapper_config, row_address_type,
multiplexing and panel_type (read at display_manager.py with these exact
fallbacks — users on non-standard panels previously had no way to
discover them from the template). vegas_scroll gains
frame_based_scrolling and scroll_delay, the only two of its 27 keys the
template omitted (read in src/vegas_mode/config.py). plugin_system gains
development_mode, which the web UI reads and writes but the template
never declared.

Every added value is byte-identical to the code-side .get() fallback, so
ConfigManager._migrate_config() merging these keys into existing user
configs cannot change behavior on any installed device.

* fix(scripts): repair broken sys.path setup in utility scripts

clear_cache.py and download_nba_logos.py pointed sys.path at a 'src'
directory relative to the script's own folder (scripts/utils/src and
scripts/src — neither exists), so both crashed on import; they now insert
the project root and import via the src package like the other scripts.
debug_web_manual.py resolved 'project root' to scripts/debug/ instead of
two levels up. fix_nhl_cache.sh is removed: it used Python docstring
syntax in a bash script and invoked clear_nhl_cache.py, which does not
exist anywhere in the repo — it cannot ever have worked in its current
location.

* docs: correct stale file:line references and the loader-fallback contradiction

CLAUDE.md and .cursorrules disagreed about plugin-directory fallback
behavior; the code (SchemaManager.get_schema_path) probes plugins/
BEFORE plugin-repos/, and the main discovery path has no fallback at
all — both files now describe the real behavior, preferring symbol names
over line numbers so the references rot slower. REST_API_REFERENCE.md
pointed at app.py:144/:607 for mounts that live at :199/:799 and counted
92 routes where there are 94. PLUGIN_ARCHITECTURE_SPEC.md's historical
banner gains a note that its example imports
(src/plugin_system/base_classes/*_plugin.py) never shipped — the real
base classes are src.base_classes.sports.SportsCore and
src.base_classes.hockey.Hockey.

PLUGIN_STORE_GUIDE.md, plugin_docs/ dir, TROUBLESHOOTING_QUICK_START.md,

check_updates.py, fix_permissions.sh) with the real tooling, and
rewrites HOW_TO_RUN_TESTS.md's CI section, which described a
security-audit workflow that was never committed and a pytest workflow
'queued to land' that landed long ago as test.yml.

* chore: remove dead modules confirmed unused in-repo and across all store plugins

- src/common/cli.py: imports a 'ledmatrix_common' package that exists
  nowhere (not in this repo, any requirements file, or the plugin
  monorepo), so it cannot ever have run; its README section claimed
  scripts/dev/* used it, which was also untrue.
- src/web_interface/logging_config.py: zero callers — the web app uses
  web_interface/logging_config.py (a different module), and nothing
  imports the src copy.
- handle_errors decorator in src/web_interface/error_handler.py: zero
  call sites (the module's response helpers stay — they are used).
- ConfigManager.get_clock_config(): reads a 'clock' config key that no
  longer exists anywhere; only caller was its own unit test.

Deliberately kept despite zero in-repo callers: DisplayError,
src/common/config_helper.py and display_helper.py — all documented as
plugin-facing API (docs/PLUGIN_ERROR_HANDLING.md, src/common/README.md),
and third-party plugins outside the official monorepo cannot be
enumerated. Verified against a fresh clone of ledmatrix-plugins (43
plugins): zero references to any removed symbol.

The four test_nba_*.py files imported nba_managers, leaderboard_manager
and odds_manager — top-level modules deleted when sports displays became
plugins — inside try/except blocks that swallowed the ImportError, so
they passed while exercising nothing. test_nba_data_structure.py and
debug_nba_api.py (a diagnostic script living in test/) made live ESPN
API calls rather than testing repo code. None were enrolled in CI.

scripts/debug/direct_fix_imports.py and check_imports.py were one-shot
artifacts that edited/inspected a hardcoded ~/LEDMatrix/web_interface/
app.py to fix an import problem solved long ago; nothing references

.github/workflows/ has no such jobs, so there is nothing for it to
aggregate and no way to run it usefully. Its siblings stay:
prove_security.py and audit_plugins.py both run standalone (verified),

* fix(web): load the three widget scripts store plugins already declare

time-picker.js, file-upload-single.js and plugin-file-manager.js
register widgets that installed store plugins reference in their config
schemas (countdown uses x-widget: time-picker and file-upload-single;
of-the-day uses plugin-file-manager), but base.html never included the
scripts. plugin_config.html renders such fields as an empty container
that polls LEDMatrixWidgets.get(...) on a 50ms loop forever, so those
plugin config fields appeared permanently blank. The audit initially
flagged these files as dead code; the monorepo cross-check proved the
opposite — they were unreachable, not unused.

example-color-picker.js (the documented custom-widget example) gains an
explicit warning that including it in base.html would shadow the
built-in color-picker widget.

* chore: drop the legacy youtube block from the secrets template

No code reads a top-level youtube secrets key: the youtube-stats plugin
receives its API key namespaced under its own plugin id (declared via
x-secret in its config schema), like every other store plugin. The key
survives only in state_reconciliation.py's non-plugin-key exclusion set,
which stays — existing installs still carry the key in their generated
config_secrets.json, and the exclusion prevents it from being
misclassified as a plugin config. New installs simply stop being asked
for a YouTube API key they have nowhere to use.

* chore(deps): remove packages nothing imports, declare direct imports, move mypy to test deps

Removed from requirements.txt: python-socketio, python-engineio,
websockets, websocket-client — zero imports anywhere in this repo, and
the one store plugin that needs Socket.IO (ledmatrix-music) declares it
in its own requirements.txt, which the plugin store installs. Removed
the same quartet plus timezonefinder, geopy, google-auth-oauthlib,
google-auth-httplib2, google-api-python-client, unidecode, icalevents,
python-dateutil, flask-wtf and the werkzeug pin from
web_interface/requirements.txt — all leftovers from the deleted built-in
weather/calendar/music displays (flask-wtf was doubly dead: app.py
explicitly disables CSRF and sets csrf=None). scripts/
install_dependencies_apt.py, which mirrors these lists for the
first-time installer, drops the same packages.

Added: urllib3 (imported directly in four core modules), jinja2 and
markupsafe (imported directly in pages_v3.py) — previously reachable
only as transitives. mypy moves from runtime requirements to
requirements-test.txt.

Verified in a fresh venv: all four requirements files co-install, pip
check is clean, the full CI-enrolled suite (907 tests) and a Flask boot
smoke pass with the trimmed dependency set.

* refactor: single canonical DateTimeEncoder

src/cache_manager.py and src/cache/disk_cache.py each defined an
identical DateTimeEncoder (datetime -> ISO-8601). The disk_cache copy is
the only one actually used for serialization; cache_manager now
re-exports it instead of defining a twin, so the two can never silently
diverge. Import compatibility is preserved — from src.cache_manager
import DateTimeEncoder still works and is the same class object.

* docs(code): document deliberate duplicates instead of merging them

The audit surfaced several near-duplicate implementations that turned
out to be either deliberate forks or behaviorally different — merging
any of them would risk changing behavior on installed devices, so each
now carries an explicit comment stating the relationship:

- VisualDisplayManager: headless fork of DisplayManager; header now
  lists the ~15 mirrored methods and warns that DisplayManager changes
  must be mirrored.
- normalize_abbreviation: LogoDownloader's version (called directly by
  nine scoreboard plugins) replaces filesystem-unsafe characters;
  LogoHelper's strips spaces. Logo filenames on existing installs
  depend on both behaviors staying put.
- The two PluginTestBase classes: the shipped one is plugin-author
  API, the repo's own richer harness lives in test/plugins/ — now
  cross-referenced.

Also verified (no change needed): ConfigManager's backup/rollback
methods genuinely delegate to AtomicConfigManager, and SportsCore
already delegates _read_bdf_native_size to FontManager.

There was no single place documenting what lives in config.json —
display.* keys were scattered across README sections, vegas_scroll lived
in ADVANCED_FEATURES.md, and dim_schedule, display.double_sided,
sync.follower_position, plugin_system.development_mode and the four
newly-templated hardware keys were documented nowhere. CONFIG_REFERENCE.md
now lists every template key plus the code-read-only keys, each with
type, default, and the code location that reads it, and explains the
secrets file's plugin-id namespacing. Linked from the docs index.

The Core Features section still presented clock/weather/sports/stocks/
music displays as built into the project, when all of them are store
plugins installed from the ledmatrix-plugins monorepo — only
starlark-apps and web-ui-info ship in this repo. The intro now says so
(the showcase itself is unchanged; those are real displays available in
the store). The display_durations reference drops its built-in-calendar
example in favor of plugin-id keys, and the Configuration section links
the new CONFIG_REFERENCE.md.

* docs: archive the custom-icons status report, cross-link config docs, document assets/

PLUGIN_CUSTOM_ICONS_FEATURE.md was a 'What Was Implemented' status
report duplicating the actual guide (PLUGIN_CUSTOM_ICONS.md) — moved to
docs/archive/ per the docs index's own policy. The overlapping
plugin-config docs keep their content but PLUGIN_CONFIG_ARCHITECTURE.md
now states up front which doc is canonical for which purpose.

assets/README.md is new and load-bearing: assets/stocks, weather,
news_logos and broadcast_logos have zero references in this repo's code,
which makes them look deletable — but store plugins (ledmatrix-stocks,
ledmatrix-weather, news, odds-ticker) resolve those exact paths at
runtime against the install directory. The README records that evidence
so a future cleanup doesn't break installed plugins.

* test: add regression guards for the bug classes fixed in this PR

Three lightweight static checks, all enrolled in CI's unit-test
allowlist along with the new web-cache test:

- test_template_targets.py: every literal render_template() target must
  exist (would have caught the weather/stocks partial 500s at commit
  time).
- test_widget_scripts.py: every widget JS file must be script-included
  in base.html or explicitly allowlisted with a reason (would have
  caught the unloaded time-picker/file-upload-single/plugin-file-manager
  widgets), and allowlisted files must NOT be included (prevents the
  example widget from shadowing the real color-picker).
- test_doc_links.py: relative markdown links in active docs must
  resolve (docs/archive/ exempt).

Each guard was verified to fail against the pre-PR tree and pass now.

Commit 1ec22db removed the werkzeug>=3.1.6,<4.0.0 pin along with the
genuinely-unused packages, but this one was a version floor on Flask's

* fix(web): route pixel_mapper_config into display.hardware; guard time-picker registration

pixel_mapper_config was the only display.hardware key absent from both
the display_fields detection allowlist and the hardware write loop in
the settings save path. No form posts it today, but if one ever did the
key would fall through to the generic handler and land at the TOP level
of config.json — where state_reconciliation would mistake it for a
missing plugin id and loop auto-repair attempts (the failure class the
'github'/'youtube' exclusion comment documents). It now round-trips
into display.hardware like its siblings.

time-picker.js gains the same LEDMatrixWidgets-undefined guard its two
sibling widgets already have; correct today only via defer ordering.

first_time_install.sh's fallback secrets heredoc (used only when the

* fix: address CodeRabbit review findings

Verified each finding against the code; fixes for the valid ones:

- install_dependencies_apt.py: the installer listed 'freetype', but the
  declared dependency is freetype-py — an apt miss would pip-install the
  wrong PyPI package. Now installs freetype-py with an import-name
  mapping (pre-existing bug, surfaced by the review).
- api_v3.py: pixel_mapper_config is validated as a string before being
  saved to display.hardware (JSON callers could previously store an
  object/list the matrix library can't use).
- .cursorrules: the Plugin Loading Process and File Organization
  sections still said discovery scans plugins/ — now consistent with the
  corrected overview (configured directory, default plugin-repos/).
- README.md: removed the stale '(except the core calendar)' claim — no
  core calendar exists in src/ — and qualified the plugin inventory
  (official plugins in the monorepo; third-party from their own repos).
- CONFIG_REFERENCE.md: hardware_mapping now shows the code fallback
  (adafruit-hat-pwm) alongside the template value.
- PLUGIN_REGISTRY_SETUP_GUIDE.md: check_plugin.py takes --plugin, not a
  positional id.
- scripts/fix_perms/fix_*.sh: exec bits set so the documented
  'sudo ./...' invocations work.
- Guard tests hardened: template guard now catches multi-line
  render_template() calls; widget guard parses actual <script> src
  values and fails if the widgets dir goes missing; type hints and
  docstrings added per repo coding guidelines.

Skipped with reasons (noted on the PR): limit_refresh_rate_hz 100-vs-90
is documented as intentional in CONFIG_REFERENCE.md; the psutil comment
already names the enforcing manifest; docs/archive/ findings are out of
scope per the docs policy (archive may rot).

* chore: remove Cursor IDE tooling, consolidate its guidance into CLAUDE.md

The maintainer no longer uses Cursor. .cursorrules, .cursorignore and the
.cursor/ tree (rules, plugin templates, a parallel 751-line plugins
guide) are removed; measurement showed near-zero literal overlap risk —
the canonical content already lives in docs/. Unique guidance worth
keeping moved before deletion:

- CLAUDE.md gains the dev workflow (dev_plugin_setup.sh, dev_server.py,
  run.py -e, check_plugin.py), the plugin-secrets namespacing contract,
  and the no-draw_image()/paste-onto-PIL pitfall.
- PLUGIN_DEVELOPMENT_GUIDE.md absorbs the plugin version-management
  rules (pre-push hook install, SKIP_TAG, version resolution order) that
  its own text previously linked out to .cursorrules for.
- The one completed plan doc (.cursor/plans/) is archived to
  docs/archive/ per the docs policy rather than deleted.

One of the deleted rule files (sports-managers.mdc) targeted
src/*_managers.py globs that have matched nothing since the plugin
migration.

* chore: second-pass cleanup — dead installer branch, broken script, orphaned JS, misfiled test deps

- first_time_install.sh: removed the pip fallback branch that installed
  from requirements_web_v2.txt — a file that has not existed since the
  v2 web interface was removed (the branch always printed its own
  'not found; skipping' warning).
- scripts/remove_plugin_backups.sh deleted: its PROJECT_ROOT resolved to
  the repo's PARENT directory, and its verify_submodules() checks for
  plugin submodules from an era before plugins moved to the store — it
  could never have worked from its current location.
- plugins_manager.js: removed three functions with zero call sites
  anywhere (addKeyValuePair, formatCommit, togglePasswordVisibility) —
  verified against all templates, all JS, and the dynamic window[name]
  dispatch sites, which resolve widget-registry keys only. Also replaced
  base.html's misleading 'Legacy ... during migration' label: the file
  is deliberately loaded last and provides the LIVE implementations of
  seven window.* plugin actions that shadow same-named definitions in
  app.js/app-shell.js.
- pytest/pytest-cov/pytest-mock moved from runtime requirements.txt to
  requirements-test.txt (CI already installs both files; the installer's
  line-by-line loop simply installs three fewer packages on devices; no
  store plugin declares pytest). HOW_TO_RUN_TESTS.md updated.
- scripts/add_defaults_to_schemas.py and analyze_plugin_schemas.py
  scanned the empty legacy plugins/ dir — now scan plugin-repos/.

Verified: fresh venv installs all four requirements files with pip check
clean and pytest available; bash -n on the installer; node --check on
the JS; widget/cache guard tests green.

* docs: correct semantically stale content across the user and developer guides

A second-pass content audit checked the guides' substantive claims
against the code (the first pass only fixed mechanical drift). Fixes:

- GETTING_STARTED: described booting a prebuilt SD image and seeing
  default clock/weather plugins — neither exists. Now documents the real
  install (Pi OS Lite + one-shot installer / first_time_install.sh) and
  that displays come from the Plugin Store. Duration and ordering
  instructions moved to the Rotation tab where the controls actually
  live.
- WEB_INTERFACE_GUIDE: three whole tabs were undocumented (Rotation,
  Backup & Restore, Tools) and the Display tab's Vegas Scroll section
  was unmentioned. Fonts overrides are per display element (not per
  plugin); Logs has an Auto-scroll checkbox (not a Pause button); the
  aspirational keyboard-shortcut list and no-JS claim removed.
- TROUBLESHOOTING: the hand-written service-file template (wrong user,
  wrong ExecStart, dropped the autostart gate) replaced with the real
  systemd/ units + install scripts; recovery steps no longer copy
  placeholder units verbatim; WiFi curl endpoint corrected to /api/v3/;
  cache-clearing advice now targets the real cache locations.
- ADVANCED_FEATURES: removed a false claim that CacheManager has no
  delete(); fixed two example snippets that raise TypeError
  (BackgroundDataService and get_config_file_mode signatures); fixed
  cache paths, a 5-minute TTL that is actually 1 hour, and the vegas
  table now links the complete 26-key reference.
- EMULATOR_SETUP_GUIDE: documented run.py flags that don't exist
  (--plugin/--test-plugins) removed in favor of dev_server.py and
  check_plugin.py; shipped emulator config values corrected (browser
  adapter default on :8888, not pygame).
- PLUGIN_QUICK_REFERENCE: drag-and-drop reordering is shipped, not
  'not yet supported'; discovery-fallback and registry-repo claims
  corrected. PLUGIN_API_REFERENCE: get_vegas_segment_width returns
  panels, not pixels. CONTRIBUTING: the repo uses flake8/mypy/bandit
  pre-commit hooks, not black/ruff, and tests need requirements-test.txt.
- SKIN_SYSTEM/DEVELOPER_QUICK_REFERENCE: stale module paths.

* fix: raise the two new dependency floors past their CVEs, silence a deliberate re-export

All three of these were introduced by this PR, which is what makes them
worth fixing here rather than deferring.

`urllib3` and `jinja2` were added to the requirements so that direct
imports stop relying on transitives — right call, but both floors were
set to the version that introduced the API rather than a version that is
safe to install. `urllib3>=1.26.0` sits below roughly ten CVEs including
a decompression-bomb safeguard bypass, and `jinja2>=3.1.0` below five
including two sandbox breakouts. Raised to 2.7.0 and 3.1.6, which is what
a working device already runs, so no install is disturbed. The comments
now say the floor is a security floor, since the next person to read
"imported directly" would otherwise reasonably lower it again.

This is the same reasoning the PR already applied to werkzeug; these two
just missed it.

The `DateTimeEncoder` import in cache_manager is unused on purpose — the
canonical class moved to src.cache.disk_cache and this re-export keeps
the documented import path working. flake8 cannot see intent, so it gets
an explicit `# noqa: F401` rather than being removed and quietly breaking
anything importing it from here. Verified the re-export still resolves to
the same object and still serialises datetimes.

* fix: address CodeRabbit re-review — installer robustness and doc lint

- install_dependencies_apt.py: an import-only check let Debian
  Bookworm's python3-freetype 2.3.0 satisfy the freetype-py>=2.5.1 pin.
  check_package_installed() now verifies the installed freetype-py
  version, and an apt install that lands below the minimum falls through
  to pip instead of counting as success.
- first_time_install.sh: the .web_deps_installed marker was created even
  when the smart installer failed, so re-runs skipped installation with
  dependencies missing. The marker is now created only on success.
- CONTRIBUTING.md: document installing the pre-commit CLI before
  'pre-commit install' (the requirements files don't provide it).
- Doc lint: fence language on the on-demand cache example (MD040),
  blockquote continuation in GETTING_STARTED (MD028), and the
  suppress_adapter_load_errors key removed from the emulator debug
  example to match the options table.

Skipped one finding with reason (noted on the PR): the per-plugin
display_duration field in PLUGIN_QUICK_REFERENCE's example is not
obsolete — BasePlugin.get_display_duration() reads it and
PLUGIN_CONFIG_CORE_PROPERTIES.md documents it as a core property;
display.display_durations is a per-mode override, not a replacement.

ChuckandClaude Sonnet 5 5b45f35888 Vegas mode: reclaim dead space and pace the rotation (#423) 
* Vegas mode: reclaim dead space and pace the rotation

On a wide panel Vegas mode spent much of its time showing black. At 50px/s
on a 512px display, one display width of blank is 10.2 seconds, which makes
several long-standing behaviours expensive:

- ScrollHelper prepended a full display width of black as an "initial gap",
  charged once per cycle — 10.2s of black at the start of every rotation.
- Plugins without get_vegas_content() are captured off a full-display canvas,
  so their blank margins entered the ticker too. Measured: of-the-day drew
  35px of "No Data" on a 512px canvas (92% blank), youtube-stats 142px of
  content with 185px of black either side. Only the scroll_helper path had
  any trimming.
- Cycle transitions deliberately pushed a blank frame and then recomposed
  synchronously: 84ms at best, 4.8s at worst, every millisecond of it black.
- buffer_ahead doubled as the cycle size, so a 21-plugin install showed 3
  plugins per cycle and took ~7 cycles to come around.
- separator_width was applied between every image rather than at plugin
  boundaries, so a per-row ticker like the F1 scoreboard (116 images, which
  it renders 4px apart internally) got a 32px chasm between each row — and
  the width budget didn't count those gaps, so the plugin quietly occupied
  far more of the panel than intended.

Changes:

- src/vegas_mode/geometry.py: numpy column-ink primitives shared by the
  trimmer and the audit tool, so the number reported is the number acted on.
  A Python per-column loop over a 17,000px strip is far too slow for the
  render path.
- PluginAdapter trims every content path, not just scroll_helper. Only outer
  edges are cropped: interior blank columns are the plugin's own layout
  (logo left, score right) and closing them would corrupt the design. A
  plugin on a non-black background is inherently unaffected.
- ScrollHelper.create_scrolling_image takes an explicit lead_gap, still
  defaulting to display_width so the many standalone-ticker callers are
  unchanged. Vegas passes lead_in_width (default 0).
- Cycle end holds the last rendered frame instead of blanking, turning the
  recompose into a brief freeze rather than the panel switching off.
- plugins_per_cycle (default 6) is split from buffer_ahead, which goes back
  to being only a prefetch low-water mark.
- max_plugin_width_ratio (default 3x display width) caps one plugin's share
  of a cycle. Overflow is deferred, not discarded: a rotation offset advances
  each fetch so later rows appear on subsequent cycles. Single oversized
  images are cropped at a blank column so the cut misses glyphs.
- Composition groups images by plugin: rows are joined by intra_plugin_gap
  (default 8) and separator_width applies only between plugins. The width
  budget now counts those gaps.
- Plugin data updates no longer run on the Vegas render path.

All new settings are user-configurable in Display -> Vegas Scroll, including
min/max cycle duration and dynamic duration, which previously existed in code
but were reachable only by hand-editing config.json.

Measured with scripts/dev/vegas_audit.py on a 512x64 panel:

  mean ink coverage    42.7% -> 69.4%
  fully blank           5.9% -> 0%
  reads as empty        13.6% -> 0%
  worst blank stretch    4.8s -> 0s
  full rotation          414s -> 123s
  plugins per cycle         3 -> 6

Note the metric choice: a "fully blank" scan (>=95% black viewport) reported
only 0.4% and badly understated the problem, because two full-width segments
with mid-canvas content never fully blank the viewport — they hold it at ~28%.
window_coverage_stats grades every viewport position by how much ink it
carries, which is what tracks perceived dead time.

Known remaining: cycle transitions still freeze ~3.5s while the next cycle is
fetched. Fixing that needs background prefetch, which is deferred because the
fallback-capture path mutates the shared display_manager.image and racing it
against the render loop risks torn frames.

* Align Vegas API bounds with validate(), fix audit config plumbing

Both from review feedback on #423.

The web API's accepted ranges disagreed with VegasModeConfig.validate(),
which is what actually gates Vegas starting:

  scroll_speed      1-100  -> 1-200   (a slider value of 150 returned 400)
  separator_width   0-500  -> 0-128
  target_fps        1-200  -> 30-200
  buffer_ahead      1-20   -> 1-5

The three loose ones were the dangerous direction: the value saved with a
200, then VegasModeCoordinator.start() failed validation with only a log
line, so the ticker silently never ran. The UI already matched validate() in
all four cases, so the API was the odd one out.

test_vegas_api_bounds_match_validate parses the numeric_fields map out of
api_v3 and asserts every bound against validate(), plus that validate()
accepts both endpoints and rejects just outside them, so these cannot drift
apart again. That test immediately caught a missing upper bound on
min_plugin_width, now added — unbounded it would drop every segment and
leave a blank ticker.

Separately, vegas_audit.py constructed PluginAdapter without the config, so
it fell back to VegasModeConfig() defaults and would report trimming and
width-budget behaviour that differed from the user's config.json. It now
passes the loaded config exactly as the coordinator does. This is the same
class of drift the explicit lead_gap and grouping arguments already guard
against. Output is unchanged on a rig whose config matches the defaults.

* Vegas mode: render plugins narrower, space rows by measured separation

Trimming reclaims blank margins but cannot compact a layout that genuinely
spans the display — a five-column forecast, a progress bar drawn at 100%
width, a stat block with the panel's whole width between its elements. Those
need the plugin to make different layout decisions, which means telling it the
screen is narrower while it renders.

DisplayManager.render_size() presents a smaller logical canvas for the
duration of a Vegas content fetch, reusing the same _LogicalMatrix
indirection double-sided mode already relies on so plugins see a consistent
size from every accessor. Plugins that size themselves from matrix.width need
no changes at all; one that wants to be explicit can read the new
BasePlugin.get_vegas_render_width().

Width is a percentage so a single setting travels across panel sizes:
vegas_scroll.render_width_pct globally, or vegas_width_pct in an individual
plugin's config. Measured on a 512x64 panel with real data:

  ledmatrix-weather   1536px -> 576px   (forecast becomes narrow cards)
  youtube-stats        353px -> 199px   (2% blank left, so genuinely compact)
  geochron             453px -> 153px   (ink density rises to 100%)
  ledmatrix-flights    950px -> 740px

The youtube-stats figure is the clearest evidence the layout itself changed
rather than being cropped: at full width the content had to be trimmed from
512px to 353px, whereas at 40% it arrives with almost no blank to reclaim.

Row spacing is now measured rather than added. A flat gap gets it wrong in
both directions at once — content drawn flush to its own edges ends up nearly
touching (reported for recent sports scores, which sat 8px apart), while
content already carrying wide margins gets pushed even further out.
separation_gap() measures the blank each pair already has and adds only the
shortfall, up to min_content_separation (default 24). intra_plugin_gap stays
as a floor applied regardless.

Two tests shipped in the previous commit encoded the old flat-gap arithmetic
and are updated to the measured semantics, including one renamed to reflect
that zero intra_plugin_gap alone no longer butts rows together.

Also fixes a real bug found while testing: the harness display manager had no
render_size(), and because the adapter catches broadly that surfaced as "no
content" rather than an error, silently dropping five plugins. Added the
context to VisualTestDisplayManager for parity, and _render_at() now degrades
to a no-op on any display manager lacking it, so a third-party or older
harness loses the narrowing rather than the content.

* Vegas mode: end cycles before the wrap, keep the width budget honest

Three fixes, the first a regression from lead_in_width defaulting to 0.

get_visible_portion wraps: once scroll_position + display_width passes the end
of the strip it fills the right of the frame from the *head* of the same strip.
So the final display_width of travel showed the cycle's first plugin re-entering
on the right while its last plugin exited on the left, and the recompose that
followed replaced both at once. On a 512px panel at 50px/s that was 10.2s of
two plugins on screen at once, ending in a hard cut — reported as the ticker
"switching mid-scroll" from F1 to news.

That used to be invisible because the strip began with a full display_width of
blank, so the wrapped-in region was black. Removing that blank (it was 10s of
dead panel per cycle) exposed the wrap. Cycles now end one display width
earlier, before any wrapped content appears, clamped for strips no wider than
the display so they don't complete instantly and spin the recompose loop.

Verified on hardware: a 3936px strip now completes at 68.5s, exactly
(3936 - 512) / 50.

Second, auto_trim=False also skipped the width budget, which is an unrelated
concern — turning off margin cropping should not let one plugin hold the panel
for minutes. Seen in the field: the F1 scoreboard contributed 116 images and
14,848px untouched, giving a 33,821px cycle (11 minutes of content). The budget
now applies regardless of trimming; with it restored that cycle is 6,362px.

Third, the budget accounted for row gaps using the flat intra_plugin_gap while
the compositor had moved to measured separation, so it under-counted by up to
(min_content_separation - intra_plugin_gap) per row and a many-row plugin
overran its cap. Both now use the same separation_gap() rule, and a test
asserts the composed block fits the budget end to end rather than trusting the
two paths to agree.

* Fix IndexError in find_blank_cut when the cut lands on the image edge

A cut position after the last column is legitimate — _crop_to_budget asks for
min(start + budget, img.width), which equals the width whenever the remaining
strip is shorter than the budget. find_blank_cut clamped target to width but
then walked leftwards starting at target itself, so ink[width] raised
IndexError.

Caught on hardware: it killed the ledmatrix-stocks fetch, and because
_fetch_plugin_content catches broadly that surfaced as the plugin silently
contributing nothing for the cycle.

Only reachable on the second or later pass of the rotating window over a single
oversized image, which is why the existing tests missed it — they all exercised
the first pass, where start is 0 and start + budget is comfortably inside the
image. Added TestRotationAcrossMultipleCycles, which walks the window round
several times and asserts content is never lost, plus direct coverage of
find_blank_cut at and beyond the image edge.

Both bounds now stop at width - 1 so neither direction can index past the end.

* Only cut oversized segments at real gaps between items

The width-budget crop snapped to the nearest blank column, and in rendered text
the gap between two characters is a single column. So a cut routinely landed
inside a word: the cycle showed "Wednesda" and the orphaned "y" turned up as a
lone floating letter in the next cycle, positioned after whatever plugin
happened to precede it.

Measured on the clock-simple segment to confirm: its blank runs are
[1, 1, 1, 1, 1, 8, 8] — five single-column letter gaps, every one of which
find_blank_cut would happily have chosen.

Cuts now only land in a run of at least min_cut_gap blank columns (default 6),
which excludes letter spacing while still finding the gaps plugins put between
items (the stocks ticker uses 32px, baseball 48px). Where no boundary falls
inside the budget the cut waits for the next one and overruns, because
splitting an item is worse than a slightly long segment.

Continuous content is treated differently on purpose: an image with no internal
gaps is a map or a chart, where any column is as good as another, so it is still
cut to the budget exactly. The gap rule protects discrete items; letting a solid
image escape the cap in its name would be wrong.

blank_runs() is vectorised — 48ms for a 17,000px strip, against seconds for a
per-column Python loop.

* Hold capture_mode for every plugin render, not just narrowed ones

The native content path only entered capture_mode when it was also narrowing
the canvas, so at full width — which is every plugin without a vegas_width_pct
override, i.e. most of them — a plugin calling update_display() while building
its Vegas content wrote straight to the hardware. That is a visible flash
mid-scroll, and it lines up with the flash reported at cycle transitions, when
several plugins are fetched back to back.

Suppression is now unconditional; the narrowing context stays separate because
it is already a no-op at full width.

Both contexts are reached through helpers that degrade to nullcontext when the
display manager lacks them. That matters more than it looks: the adapter's
handlers are deliberately broad, so an AttributeError from a missing context
does not surface as an error — it surfaces as the plugin contributing nothing.
Making the call unconditional without this turned 44 tests red for exactly that
reason, all of them reporting lost content rather than the real cause.

The test double now provides capture_mode and render_size too, so tests
exercise the real contexts instead of silently taking the degraded path.

* Vegas mode: one continuous strip instead of swapping cycles

A cycle used to be a discrete strip that got replaced: motion stopped, every
pixel was substituted at once, and the next group started with the viewport
already full. That is the freeze, the flash and the jump.

The strip is now extended rather than replaced. ScrollHelper gains
append_content(), which adds items on the right without touching
scroll_position or total_distance_scrolled, so motion continues and the next
group simply arrives from the right. Because completion is measured against
total_scroll_width, extending also defers completion — there is no longer a
cycle boundary to see.

drop_scrolled_prefix() reclaims what has gone past, keeping the strip bounded
however long Vegas runs (observed 5,000-11,000px against an unbounded strip
otherwise). It shifts total_distance_scrolled and total_scroll_width together so
the completion arithmetic is unchanged, and refuses to run while the viewport is
wrapping: wrapping reads the head of the strip into the right of the frame, so
trimming the head there would visibly change the picture. A test caught that.

Groups are prepared off the render thread. The constraint is that the canvas and
the matrix proxy are process-wide mutable state, so narrowing or capturing
through them from another thread would corrupt the frame the render loop is
pushing. get_content() therefore takes offscreen_only: the background thread uses
only paths that avoid the canvas, and anything needing it is marked and picked up
on the render thread. That puts the expensive work (native renders of leaderboard
and baseball cards, seconds each) in the background and leaves the cheap work
(display capture, 40-600ms) in the foreground.

DisplayManager's capture flag is now thread-local. As a shared flag, a background
capture would have suppressed the render loop's own frame pushes for its
duration, freezing the panel precisely when the point was to avoid a freeze.

Canvas-bound plugins are drained one at a time rather than as a batch: six at
once held the render thread for 1.75s. Drains are also spaced by two seconds
while the lookahead is healthy, since taking them back to back turns one long
stall into a run of short ones. When the strip is genuinely running short the
throttle is ignored, because content matters more than smoothness there.

Measured on hardware: zero cycle-complete swaps, drains landing 2-4s apart,
lookahead holding at 1,200-3,500px, no errors.

Set continuous_scroll false to restore the swap behaviour; the old path is intact.

* Pace the Vegas frame loop adaptively: 31.5 -> 78.7 fps

The loop slept a fixed frame_interval on top of however long the frame took, so
at a measured 31.6ms per frame a flat 8ms of that was pure idle — a quarter of
the budget spent not rendering. It now sleeps only the remainder of the budget.

Measured on hardware: 31.5 fps to 78.7 fps sustained, with CPU going *down* from
150% to 127%. Scroll speed is unchanged at 49.9px/s against a configured 50,
because motion is derived from elapsed time rather than frame count — this buys
smoothness, not speed.

Worth recording what the bottleneck was not: the per-frame render path measures
0.34ms in total (0.18ms for the numpy slice, 0.17ms for the dirty-tracking
digest), which is a theoretical 2900 fps. Optimising any of that would have been
wasted effort. The frame was idle, not busy.

Also nices the prefetch thread. Its work is PIL and numpy that releases the GIL,
so the scheduler can act on the priority, and without it the prefetch competes
for the same cores as the render loop.

* Sub-pixel scrolling: motion at the frame rate, not the pixel rate

With integer positioning the number of distinct frames per second equals the
scroll speed in px/s, however fast the loop renders. Measured at 50px/s and
78.7fps, 36% of frames were byte-identical: the extra frames cost work and
bought no motion, and what was left was 50 discrete 1px steps a second.

Two things were wrong with the pre-existing sub-pixel support. get_visible_portion
never consulted sub_pixel_scrolling — it always took the integer path, so the flag
and _get_visible_portion_subpixel were dead code. And that implementation needed
scipy.ndimage.shift, which is not installed on the target devices (HAS_SCIPY is
False there), so it would not have interpolated even if reached. Verified both:
positions 1000.0 and 1000.5 produced identical frames either way.

Blending is now wired up and implemented with numpy. Two details make it
affordable: slice cached_array directly instead of building two PIL images only
to convert them straight back (the naive version measured 15x the integer path),
and use fixed-point uint16 multiply-add rather than float32, which suits the Pi's
cores and gives finer weighting than the panel can resolve. Result 0.939ms
against 0.237ms — 0.70ms added per frame, a 1065fps ceiling.

Measured on hardware: 81.2 fps with blending on, against 78.7 with it off, so no
cost within noise — and every frame is now a distinct position rather than one in
three being a repeat.

The trade is a slight horizontal softening of text, since each frame blends two
positions. Set smooth_scroll false for maximum crispness.

Also benchmarked and cleared as non-issues: extending the strip costs 9.4ms on an
11,000px strip and trimming 2.5ms, both under one frame at this rate.

* Add overflow handling: keep ordered content whole instead of rotating a window

The width budget split any oversized plugin by advancing a window each cycle.
That is right for interchangeable items — news headlines, odds, stock prices —
but wrong for ordered content: a league table showed ranks 1-6, then resumed at
7 two rotations later, which reads as out of order and out of context. Nobody
needs rank 23 in a ticker; they need the top of the table, every time.

overflow_mode chooses between them:

  rotate   — advance a window each cycle so everything is seen eventually
             (unchanged default)
  truncate — always show the start and drop the rest, keeping ordered content
             coherent. Records no window state, so every pass starts at the top.

Per-plugin vegas_overflow overrides the global setting, since one install has
both kinds of plugin. Also adds per-plugin vegas_max_width_screens, so content
that must stay whole can be given more room — or uncapped with 0 — without
lifting the cap on every ticker.

Applied on the test rig: f1-scoreboard and ledmatrix-leaderboard set to
truncate, and baseball given 4.5 screens because it was showing 8 of 9 games
when the whole slate needed only a little more room. Verified: F1 now reports
"the first 10 of 116 ... the rest are not shown", baseball has dropped out of
the budget log entirely, and stocks, odds-ticker and stock-news still rotate.

Also corrects the crop log, which claimed "window advances next cycle"
unconditionally and so misreported truncated crops. A test now pins the
behaviour behind the message: truncate must leave no offset recorded.

* Stop Vegas mode showing last night's games as if they were live

A game that was live in the evening was still being drawn as live the next
morning. Two faults combined to freeze plugin visuals indefinitely.

PR #291 added a call to plugin_adapter.invalidate_plugin_scroll_cache() so
a plugin's own cached scroll image would be rebuilt from fresh data. That
method was never implemented. hot_swap_content() wraps the call in a broad
except, so every hot swap has raised AttributeError and been swallowed
silently ever since — which is why the visuals it was meant to keep fresh
never were.

Continuous scrolling then removed the only path that reached it at all:
should_recompose() and hot_swap_content() are called from the
non-continuous branch of run_frame(), and continuous_scroll defaults to
True. So on a default install the pending-update flags were set by the
update tick, never consumed, and grew without bound.

Together these froze content completely, because refetching is not enough
on its own: the sports plugins' get_vegas_content() regenerates only "if
the cache is empty", so take_next_group() kept receiving the same picture
however often it asked.

Fixed by:

- Implementing invalidate_plugin_scroll_cache(). It covers both layouts —
  a helper directly on the plugin (stocks, news, odds-ticker) and one
  owned by a scroll-display manager (the sports scoreboards, which is the
  shape that produced this bug) — and clears cached_image and
  cached_array together, since the array is the image's numpy mirror.

- Adding StreamManager.invalidate_pending_updates() and calling it from
  the continuous branch. It only drops the caches; the plugin recomposes
  when it next comes round in the rotation. process_updates() is wrong
  here: it refetches synchronously and merges into the active buffer that
  continuous mode bypasses, and hot_swap_content() rebuilds and
  repositions the whole strip, which is the freeze-and-jump this mode
  exists to avoid.

Tests assert the fix rather than the implementation: 14 of the 17 new
tests fail without it. Includes the wiring itself, since the regression
was a call that was simply absent, and a check that the scroll position is
untouched so this cannot regress into the swap's visible jump.

All Vegas suites pass (355 tests). test_display_controller_vegas_tick.py
still cannot be collected off-device for want of rgbmatrix, identically
with and without this change.

test_prepared_group_is_used_without_refetching had a tautological final
assertion; now checks stream.calls directly. test_no_partial_letter_at_either_edge

crop's start position with no lead-in gap in word_strip, so it legitimately
carries ink — only the right edge is an actual cut and needs the check.

* fix(testing): add MockCacheManager.get_cached_data_with_strategy/save_cache

ledmatrix-leaderboard's data_fetcher.py calls these two real-CacheManager
methods (src/cache_manager.py:313,817), but MockCacheManager had neither --
update() always hit an AttributeError, caught by a broad except and logged,
so the harness rendered an empty-but-green leaderboard on every test run
without ever exercising real standings data.

Both mocks delegate to the existing get()/set() -- a mock doesn't need the
real strategy's per-data-type max_age/market-hours timing, plugins under
test just need the methods to exist and round-trip whatever was cached.

* fix(testing): clear get_cached_data_with_strategy_calls in MockCacheManager.reset()

reset() cleared get_calls/set_calls/delete_calls but not the newer
get_cached_data_with_strategy_calls tracker, so a reused mock (e.g. across
test cases sharing a fixture) retained stale strategy-call records after
reset().

Chuck 3d347a368a fix(testing): stop plugin enabled:false schema defaults from silently disabling harness tests (#408) 
check_plugin.py, render_plugin.py, and the pytest plugin matrix each built
config as {"enabled": True} then merged in config_schema.json's defaults on
top, letting a plugin's own enabled:false default (a reasonable choice for
a seasonal/opt-in plugin -- 15 of 23 real plugins ship one) silently win.
Every harness/CI render of those plugins was testing "disabled, do
nothing" rather than real behavior.

Extract build_full_config() into testing/loading.py (already the shared
home for plugin-discovery/config-default logic) and use it from all three
call sites: schema defaults, then a forced enabled=True, then harness.json's
config, then the caller's explicit config -- so a test can still
deliberately disable a plugin on purpose, it just can't happen by accident
via the plugin's own shipped schema default anymore.

 		7f7f0d6464 feat: adaptive layout system — size-aware regions, crisp font ladders, image fitting (#393) 
* feat(layout): adaptive layout & font scaling system for plugins

Add src/adaptive_layout.py — opt-in core helpers so plugins render
legibly on any panel size without hand-tuned per-display layouts:

- Region: integer rect algebra (bands/columns/weighted splits/centering)
  that partitions space so text bands can't overlap by construction
- Font ladders: ordered (family, size) steps known to render crisply
  (LADDER_GRID: X11 BDFs at native sizes; LADDER_ARCADE: PressStart2P at
  8px multiples) — fitting walks the ladder instead of scaling pixel
  fonts fractionally
- LayoutContext: breakpoint tiers, geometry scale vs. a declared design
  size, and cached fit_text/fit_lines/font_for_rows queries

Generalizes the three patterns proven in the field: f1-scoreboard's
scale factor, masters-tournament's tiers, baseball-scoreboard's font
fallback ladder.

Wiring: BasePlugin gains a lazy .layout property and draw_fit();
FontManager gains get_native_bdf_size() and a cache_generation counter;
manifest schema gains display.design_size and requires.display_size
max_width/max_height; 96x48 joins DEFAULT_TEST_SIZES; the bounds-check
harness records negative-coordinate draws; TextHelper's broken
measurement helpers are fixed.

- fit_image(img, box, mode=contain|cover|fill_height|stretch,
  crop_to_ink, anchor, resample, upscale) promoting the proven plugin
  patterns (football's crop-to-ink fill-height logos, masters' cover
  crop + NEAREST flags, static-image's letterbox). Upscales by default —
  thumbnail()'s downscale-only behavior is why imagery stays tiny on
  big panels.
- draw_fitted_image() pastes aligned within a Region with alpha mask.
- One central Pillow>=9.1 RESAMPLE shim replacing ~15 plugin copies.

LayoutContext.fit_image() caches results per (identity, box size,
options) with a 64-entry LRU; id()-keyed entries pin the source image.
BasePlugin.draw_image() is the one-liner adoption path beside draw_fit.

Composites in adaptive_layout.py: Region.offset() (user x/y-offset
passthrough), scoreboard_regions() (the two-logos-plus-score card math
duplicated across six sports plugins, logo_slot = min(H, W//2)), and
media_row() (art-left/text-right).

Fix LogoHelper's size-blind cache key (stale sizes on panel change);
deprecation note on dead image_utils.py.

* feat(harness): scale-up fill check, config variants, multi-size dev gallery

Quality gates for adaptive layout:

- fill_metrics()/check_scale_up() in the safety harness: overflow catches
  content too big for a panel, but nothing caught content that stays tiny
  on panels >= 2x the plugin's declared design size. The check measures
  lit-content extents and warns (or fails, when a plugin opts into
  "fill_check": "strict" in test/harness.json) below 50% coverage on the
  doubled axis. Warn-only by default so no existing plugin breaks.

- harness.json "variants": extra runs with config overlays and their own
  golden dirs, so an opt-in mode (e.g. layout_mode: adaptive) is golden-
  tested beside the classic default. check_plugin.py loops base + variants
  and labels variant results mode@name.

- Dev preview server: GET /api/sizes (harness size sample), POST
  /api/render-matrix (render at up to 12 sizes in one call), size-preset
  dropdown, and an "All Sizes" side-by-side gallery in the preview UI.

* feat(plugins): adaptive-lib discoverability + advisory version compat warning

Discoverability: re-export the adaptive layout/image API from src.common
(the blessed-helpers package plugin authors already know) — canonical
paths stay src.adaptive_layout / src.adaptive_images so nothing breaks.
Document it in src/common/README.md and cross-link ADAPTIVE_LAYOUT.md
from the developer docs authors actually read (quick reference, API
reference, advanced dev, font manager, dev preview, plugin dev guide);
ADAPTIVE_LAYOUT.md gains adaptive-images, composite-layouts and
preserving-user-customization sections.

Compat: PluginLoader now logs one advisory warning (never raises) when a
plugin's manifest declares a min LEDMatrix version newer than the running
core, checking the min_ledmatrix_version / requires.* / versions[]
spellings found in the wild. Guarded against stale core version numbers.

src/__init__.py __version__ bumped 1.0.0 -> 3.1.0 to match the latest
release tag (v3.1.0) — it had never been updated and the compat check
needs a truthful number. NOTE: verify this matches the intended release
numbering before the next tag.

* feat(layout): add measure_font_crispness — verify a ladder rung isn't blurry

PIL antialiases TTF outlines by default; a 'pixel-style' font only
rasterizes without antialiasing at specific sizes (for PressStart2P:
exact multiples of its 8px design grid). A ladder rung at an unverified
size silently renders blurry on an LED panel — this exact bug shipped in
both text-display's and football-scoreboard's custom TTF ladders
(non-8-multiple PressStart2P sizes, and '5by7.regular'/'4x6-font' at
sizes that were never actually crisp).

measure_font_crispness(font, sample_text) renders the sample and reports
the fraction of ink-bbox pixels that are neither pure black nor pure
white. BDF fonts (real bitmaps) always score 0.0; TTF ladders should be
verified against this before shipping — see the new
TestFontFitting::test_ladder_arcade_is_crisp pattern.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(layout): add fit_text_proportional — proportional sizing vs. always-maximize

fit_text always picks the largest ladder rung that fits its box. That's
right when an element owns dedicated space, but wrong when several
independently-fitted elements need to stay visually harmonious as the
panel grows: a score's box might have generous room while a neighboring
logo scales by a fixed geometry factor via px() — fit_text lets the score
balloon out of proportion (even overlapping the logo) even though its
individual pick is technically correct.

fit_text_proportional(text, box, base_size_px, ladder) instead targets
base_size_px * self.scale (the same scale factor px() already uses),
picking the nearest ladder rung at or below that target, still capped to
what fits the box, floored at the smallest rung when the target is below
every rung. Refactored the shared largest-that-fits/ellipsize walk into
_walk_ladder() so fit_text and fit_text_proportional don't duplicate it.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(layout): fit_text_proportional gains an axis-specific scale override

self.scale (min(width_ratio, height_ratio)) is the right conservative
default for anything whose aspect ratio matters, but a caller whose
surrounding composition already scales along a single axis — e.g.
football-scoreboard's logo_slot = min(height, width // 2), which tracks
height alone — needs text sized the same way, or it reads as
under-scaled next to logos that grew on a panel that only got taller
(128x32 -> 128x64: self.scale stays 1.0 since width didn't grow, but
logos still double).

fit_text_proportional(..., scale=None) now accepts an explicit override;
None keeps the existing self.scale default.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(layout): scoreboard_regions reserves real center space at 2:1 aspect ratios

logo_slot = min(height, width // 2) has a blind spot: at exactly 2:1
aspect ratio (width == 2 * height -- a very common shape: two, four, or
more square modules stacked into a taller panel) width // 2 and height
are equal, so the two logo slots claim the ENTIRE width and leave zero
pixels for a center column, no matter how large the panel gets. Not a
'small panel' problem -- 96x48, 128x64, and 256x128 (all exactly 2:1) hit
it identically, while the 128x32 design baseline and panels like 192x48
or 256x32 never do, because height is already the tighter constraint
there.

Two new parameters fix it in the one shared helper every scoreboard-style
plugin composes through:

- min_center_fraction / min_center_design_px reserve at least
  max(width * fraction, design_px * ctx.scale) for the center column,
  capping logo_slot further when needed. The scaled design-px term
  matters on small panels where a flat fraction alone reserves too little
  absolute space.
- score_bleed_fraction extends the score's own fit box (not the logo
  slots themselves) a controlled amount into each side -- the same way
  real broadcast scoreboards let a big score number's edges cross into
  the team marks flanking it. Without this the reserve alone can still be
  too narrow for a short score to render without truncating.

score_area is now genuinely narrower than the full card width (previously
identical to status_band/detail_band, which still span the full width and
overlay the logos -- short text there was never the problem).

Verified against the full harness size spread: a real game score like
'17-21' never needs ellipsis at any tested 2:1-or-tighter aspect ratio
(test_score_never_needs_ellipsis_for_a_short_score), and wide panels
(128x32/192x48/256x32-style) are provably unaffected.

* fix: address CodeRabbit review on PR #393

- docs: scope the self.layout note to BasePlugin subclasses (others build
  a LayoutContext directly) and make explicit that adaptive layout is
  opt-in — classic rendering stays unless a plugin adopts the APIs.
- dev_server: broaden the render-request catch (a bad manifest.json now
  returns a clean 400 instead of an unhandled 500) and stop echoing raw
  exception text in the loader-failure responses — full tracebacks go to
  the dev server's console log instead.

* fix(dev-server): allowlist plugin_id before any path lookup

CodeQL (py/path-injection): plugin_id arrives in request input and flows
into filesystem paths via find_plugin_dir. Gate it with the same
^[a-zA-Z0-9_-]{1,64}$ allowlist the web UI's pages_v3 uses, at the
single choke point every route resolves through.

* fix(dev-server): lexical containment check on resolved plugin dirs

CodeQL doesn't recognize the interprocedural allowlist as a

* fix(dev-server): inline normpath containment barrier before render

CodeQL doesn't credit the sanitization inside find_plugin_dir along
this flow; apply its documented barrier (normpath + startswith against

that reaches the render/load sinks.

* fix(dev-server): derive plugin dir from trusted directory listings

CodeQL's barrier-guard recognition doesn't see a startswith check
inside an any() comprehension, so the normalize-and-prefix approach
still flagged. Break the taint outright instead: after lookup, re-derive
the directory by enumerating the search dirs (iterdir) and matching by
path equality — the Path used for all downstream file access is built
solely from trusted listings, never from request input.

Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam

* fix(dev-server): use os.scandir for path-injection barrier, redact stack traces from render responses

CodeQL doesn't model Path.iterdir() as a taint-clearing enumeration the
way it does os.scandir() -- _trusted_plugin_dir's iterdir-based rebuild
still traced plugin_id through to the manifest.json open(). Switched to
scandir, matching the pattern already verified clean on PR #396.

Also stops surfacing raw exception text (update()/display() failures)
in the JSON render response -- logs full detail server-side via
exc_info instead, returning only the exception class name to the
client. And drops path values from three plugin_loader debug/error
logs that CodeQL flags as clear-text-logging of externally-influenced
data, keeping plugin_id (not flagged) for context.

* fix(dev-server): remove conditional-reassignment ambiguity in plugin_dir resolution

CodeQL's path-injection flow still traced through _parse_render_request
after the scandir fix -- the tainted find_plugin_dir() result and the
scandir-derived _trusted_plugin_dir() result shared the same variable
name (plugin_dir), reassigned only on the truthy branch. That merge
point apparently isn't treated as a barrier by the flow analysis, so it
kept tracing the pre-reassignment value through to the manifest open().

Split into two distinct names -- candidate_dir (tainted, used only to
call _trusted_plugin_dir) and trusted_dir (the only name used for any
downstream file access) -- so there's no reassigned variable for the
flow to walk through.

* fix: remove unused imports flagged by Codacy

Union in adaptive_images.py and field in adaptive_layout.py are both
imported but never used -- the last two Codacy findings on this PR,
matching the same fix already applied on PR #396.

* fix(layout): bound the fit cache; never alias the source image in fits

Two latent issues found in a self-review pass:

- LayoutContext._fit_cache was an unbounded dict (the image cache got an
  LRU cap, the text-fit cache didn't). Cache keys embed the fitted TEXT,
  so a plugin fitting changing strings — a live game clock, a ticker —
  on a 24/7 service grows it forever. Now LRU-bounded at 512 entries via
  the same pattern as the image cache.

- fit_image returned the caller's ORIGINAL image object when the source
  was already RGBA at target size (contain/fill_height, no ink crop).
  ImageFitResult is documented as an independent copy, and LayoutContext
  caches results — an aliased image lets later mutations of the source
  corrupt cached fits (or vice versa). Copy in that branch.

Both covered by new regression tests.

Chuck 2ffc57cf40 fix(plugin-harness): add no-op process_deferred_updates to test double (#391) 
The safety harness's VisualTestDisplayManager (base of
BoundsCheckingDisplayManager) doesn't implement process_deferred_updates(),
which 5 first-party ledmatrix-plugins call unconditionally between
set_scrolling_state() and their scroll-position update: news, odds-ticker,
ledmatrix-leaderboard, stock-news, and ledmatrix-stocks. Any of them fails
the harness with AttributeError the moment it's touched (surfaced when
ledmatrix-plugins#177 had to add a local hasattr guard in ledmatrix-stocks
just to pass CI). Add the method as a no-op, mirroring the existing
"no-op for testing" pattern already used for set_scrolling_state, so these
plugins render under the harness without every touching PR needing its own
guard.

* feat(testing): add cross-size/cross-screen plugin safety harness

Render every plugin across all supported matrix sizes (64x32, 128x32,
128x64, 256x32) and every declared screen, failing on crashes, content
drawn past the panel edge, or visual drift vs committed golden images.

- BoundsCheckingDisplayManager: oversized-canvas overflow detection
- harness.py: multi-size/multi-screen render engine + golden compare
- scripts/check_plugin.py: CLI (functional+bounds, --out-dir, --update-golden,
  --freeze-time); render_plugin.py refactored onto shared loading helpers
- test/plugins/test_harness.py + test_plugin_matrix.py (parametrized,
  honors per-plugin test/harness.json; skips when no plugins present)
- MockCacheManager.cache_dir so cache-dir-using plugins load headlessly
- .github/workflows/test.yml + docs/plugin-safety-harness.md

* fix(testing): address PR review feedback on plugin safety harness

- check_plugin: friendly error for non-numeric --sizes; reject non-object
  --config / --mock-data JSON; sanitize plugin mode before using as a

- bounds_display_manager: pad the canvas out to the largest supported panel
  (not a fixed 16px) so far-overshoot coordinates are caught, not clipped
- harness: merge config_schema defaults inside render_plugin_matrix; surface
  update() failures as a non-fatal warning + result field instead of a debug
  log; sanitize mode in golden_path
- loading: fail fast when harness.json references a missing mock_data fixture
- mocks: clean up the per-instance temp cache dir via weakref.finalize
- test_plugin_matrix: add a discovery guard that fails when
  LEDMATRIX_REQUIRE_PLUGINS=1 but none found (still skips locally); type hints
- bound test deps with upper version pins for deterministic CI

* feat(testing): render plugins across arbitrary panel sizes, not a fixed list

Addresses maintainer feedback that there is no canonical set of supported
panel sizes — a build can be any size/configuration (square, 2x2, 4x4, 8x2,
long strips, tall stacks).

- sizes.py: SUPPORTED_SIZES -> DEFAULT_TEST_SIZES (back-compat alias kept),
  reframed as a representative SAMPLE of real panel-grid arrangements rather
  than an authoritative list; add parse_size_token / coerce_sizes /
  resolve_test_sizes helpers
- sizes are now fully overridable: LEDMATRIX_TEST_SIZES env (global, e.g. test
  on your exact hardware) > per-plugin harness.json "sizes" > default sample;
  CLI --sizes unchanged
- bounds_display_manager: pad the canvas to the largest panel IN THE CURRENT
  RUN (via overflow_extent) instead of a hardcoded max, so cross-size overflow
  detection scales to whatever sizes a run uses
- harness: compute per-run extent and thread it into the bounds manager
- tests: arbitrary-shape + size-parsing/precedence coverage
- docs: rewrite "Supported sizes" -> "Sizes: a sample, not a fixed list"

* fix(testing): fail the harness on non-connectivity update() errors

Addresses the remaining review thread: recording every update() exception as a

display() survived. Now update() failures are classified — a tolerated set of
connectivity errors (ConnectionError/TimeoutError/socket/ssl/urllib/http/
requests) is recorded non-fatally (expected with no network in CI), while any
other exception is treated as a genuine bug and fails that render.

  Codacy medium "Try, Except, Pass" (harness.py L52) and Ruff S110/BLE001.

* fix(js): resolve ESLint no-undef warnings across 6 JS files

Three distinct patterns:

1. Vendor library globals — htmx is injected by <script> before these
   extension files load; ESLint lints files in isolation and doesn't know.
   Fix: add /* global htmx */ to htmx-sse.js and htmx-json-enc.js.

2. Cross-file globals — showNotification is defined as window.showNotification
   in app.js/notification.js but called bare in app.js and error_handler.js.
   ESLint doesn't connect window.X = Y with a bare call to X.
   Fix: add /* global showNotification */ to app.js and error_handler.js.

3. Forward-reference window.* functions — in array-table.js, checkbox-group.js,
   and custom-feeds.js, functions like removeArrayTableRow are called early
   inside event-handler closures but assigned to window.* later in the file.
   At runtime this works (the handler fires after the assignment), but ESLint
   sees the bare name at the call site.
   Fix: change bare calls to window.removeArrayTableRow(this) etc. so the
   reference is explicit and ESLint-safe.

Also guard the updateSystemStats call in app.js reconnectSSE: the function
is called but defined nowhere in the codebase. Guard with typeof check so
it won't throw ReferenceError if the reconnect path is hit.

  Object.prototype.hasOwnProperty.call(DAY_LABELS, x)
  Safe form that works even on null-prototype objects

useIterableCallbackReturn:
- file-upload.js, notification.js: forEach(x => expr) →
  forEach(x => { expr; }) — forEach ignores return values;
  implicit return from arrow body was misleading

htmx-sse.js is a vendor extension file with old-style var/== patterns
that are correct for it; 18 Biome issues suppressed via Codacy API

B110 (try/except/pass):
- display_controller.py: narrow 'except Exception' to 'except AttributeError'
  for get_offset_frame() — plugins not having this optional method is the
  expected case, not all exceptions
- config_manager.py: B110 already resolved by the earlier removal of the
  dead secrets-loading block (the except/pass was inside it)
- All other except/pass blocks in src/ and web_interface/ are intentional
  (last-resort recovery, best-effort fallbacks, non-critical startup probes).
  Annotated each with # nosec B110 and a brief inline reason so the decision
  is explicit for future reviewers.
- Test files and plugin-repos B110 suppressed via Codacy API (not prod code).

B108 (/tmp usage):
- permission_utils.py: /tmp listed to PREVENT permission changes on it — not
  used as a temp path. Annotated # nosec B108.
- display_manager.py: fixed snapshot path is intentional (web UI reads same
  path); path-check guard also annotated.
- wifi_manager.py: named /tmp files match the sudoers allowlist installed with
  the system (the paths are hard-coded in both places by design). Annotated
  all six open/cp references # nosec B108.
- scripts/render_plugin.py: dev script default overridable by user. Annotated.
- web_interface/app.py: reads the same fixed path written by display_manager.
  Annotated # nosec B108.
- Test files suppressed via Codacy API.

* fix: address remaining Codacy security findings

Flask debug=True (real fix):
- web_interface/app.py: debug=True in __main__ block exposes the Werkzeug
  interactive debugger (arbitrary code execution). Changed to
  os.environ.get('FLASK_DEBUG', '0') == '1' — off by default, opt-in
  via environment variable for local development.

nosec annotations (accepted risk with documented rationale):
- disk_cache.py: os.chmod(0o660) is intentional — web UI and LED matrix
  service share a group, 660 gives group write while denying world access
  (B103 + Semgrep insecure-file-permissions suppressed in Codacy)
- wifi_manager.py: urlopen to hardcoded connectivity-check.ubuntu.com URL
  (B310 — no user input involved)
- font_manager.py: urlretrieve URL comes from user's own config file on
  their local device (B310)
- start_web_conditionally.py: os.execvp with both sys.executable and a
  fixed PROJECT_DIR-relative constant (B606)

Confirmed false positives suppressed via Codacy API (15 issues):
- SSRF (3x): client-side JS fetch — SSRF is server-side; browser fetch
  is CORS-restricted to same origin
- B105 (3x): test fixtures use dummy secrets by design; store_manager
  checks for the placeholder string, it is not itself a secret
- PMD numeric literal (2x): 10000000 is within Number.MAX_SAFE_INTEGER
- Prototype pollution (1x): read-only schema traversal, no writes
- no-unsanitized_method (1x): dynamic import() is CORS-restricted
- detect-unsafe-regex (1x): operates on server-controlled config values
- plugin-repos B103 (1x): vendor code chmod on executable
- Semgrep insecure-file-permissions (3x): same disk_cache 0o660 as above

* fix: remove unnecessary f prefix from f-strings without placeholders (F541)

Pyflakes F541 flags f-strings that contain no {} interpolation — they are
identical to plain strings but trigger unnecessary string formatting overhead.

Fixed in production code:
- src/base_classes/data_sources.py (2 debug log calls)
- src/logo_downloader.py (1 error log)
- src/plugin_system/store_manager.py (5 strings across 3 log calls)
- src/web_interface/validators.py (1 return value)
- src/wifi_manager.py (4 log/message strings)
- web_interface/start.py (1 print)

F541 issues in test/, scripts/, and plugin-repos/ suppressed via Codacy API
as non-production code.

* chore(dev): add Pillow compatibility smoke test script

Covers all Pillow APIs used in LEDMatrix — image creation, drawing,
font metrics, LANCZOS resampling, paste/alpha_composite, and PNG I/O.
Run after any Pillow version bump to catch regressions before deploy.

    python3 scripts/dev/test_pillow_compat.py

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: resolve 8 new Codacy issues introduced by PR changes

shellcheck SC2034:
- first_time_install.sh: 'type' loop variable also unused in the wifi
  status loop (we previously fixed 'device' → '_' but left 'type').
  Changed to '_ _ state' since neither device nor type is referenced.

ESLint no-undef:
- app.js: typeof guards don't satisfy no-undef; added updateSystemStats
  to the /* global */ declaration alongside showNotification.

nosec annotation:
- web_interface/app.py: app.run(host='0.0.0.0') line changed when we
  fixed debug=True, giving it a new issue ID. Re-added # nosec B104.

pyflakes F401:
- scripts/dev/test_pillow_compat.py: ImageFilter was imported but never
  used in the smoke test. Removed from the import.

Codacy API suppressions (false positives on changed lines):
- disk_cache.py 0o660 chmod (2x): lines changed when # nosec B103 was
  added, producing new Semgrep issue IDs. Re-suppressed.
- pages_v3.py raw-html-concat: Semgrep does not recognise escape() as
  a sanitizer; the escape() call IS the correct fix.
- app.py flask 0.0.0.0: same line as B104 above; Semgrep rule also
  re-suppressed.

* fix: address PR review findings

Fix (10 of 15 findings):

plugin-repos/march-madness/requirements.txt:
  Add urllib3>=1.26.0 — manager.py directly imports from urllib3; it was
  an undeclared transitive dependency via requests.

scripts/dev/dev_plugin_setup.sh:
  Restore subshell form (cd "$target_dir" && git pull --rebase) || true
  so the shell's working directory is not permanently changed after the
  if-cd block. Previous fix for SC2015 leaked cwd into the remainder of
  the script.

src/base_classes/sports.py:
  Narrow 'except Exception' to 'except RuntimeError as e' and log via
  self.logger.debug — Path.home() raises only RuntimeError for service
  users; other exceptions should not be silently swallowed.

src/config_service.py:
  Fix stale "MD5 checksum" in ConfigVersion.__init__ docstring (line 40);
  the implementation uses SHA-256 since the Codacy fix.

src/wifi_manager.py:
  Log the last-resort AP enable failure with exc_info=True instead of
  silently passing — failure here means the device may be unreachable.

web_interface/blueprints/pages_v3.py:
  Log the outer metadata pre-load exception at debug level instead of
  swallowing it silently; schema still loads fully below.

src/background_data_service.py:
  Remove unused 'timeout' parameter from shutdown() — executor.shutdown()
  does not accept timeout; update __del__ caller accordingly.

src/font_manager.py:
  Validate URL scheme before urlretrieve — reject non-http/https schemes
  (e.g. file://) to prevent reading local files from config-supplied URLs.

src/plugin_system/plugin_executor.py:
  Simplify redundant except tuple: (PluginTimeoutError, PluginError,
  Exception) → Exception, which already covers the others.

test/test_display_controller.py:
  Mark empty test_plugin_discovery_and_loading as @pytest.mark.skip with
  reason. Move duplicate 'from datetime import datetime' to module header
  and remove the stray mid-module copy.

Skip (5 of 15 findings, with reasons):
  - pytest 9.0.3 concerns: full suite already verified (467 pass, 18 pre-existing)
  - Pillow 12.2.0 API concerns: no deprecated APIs in codebase; tests + Pi smoke test pass
  - diagnose_web_ui.sh sudo validation: set -e already ensures fail-fast on any sudo failure
  - app.py request-logging except: must stay silent (recursive logging risk); annotated
  - app.py SSE file-read except: genuinely transient I/O; annotated

 		23f0176c18 feat: add dev preview server and CLI render script (#264) 
* fix(web): wire up "Check & Update All" plugins button

window.updateAllPlugins was never assigned, so the button always showed
"Bulk update handler unavailable." Wire it to PluginInstallManager.updateAll(),
add per-plugin progress feedback in the button text, show a summary
notification on completion, and skip redundant plugin list reloads.

* feat: add dev preview server, CLI render script, and visual test display manager

Adds local development tools for rapid plugin iteration without deploying to RPi:

- VisualTestDisplayManager: renders real pixels via PIL (same fonts/interface as production)
- Dev preview server (Flask): interactive web UI with plugin picker, auto-generated config
  forms, zoom/grid controls, and mock data support for API-dependent plugins
- CLI render script: render any plugin to PNG for AI-assisted visual feedback loops
- Updated test runner and conftest to auto-detect plugin-repos/ directory

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix(dev-preview): address code review issues

- Use get_logger() from src.logging_config instead of logging.getLogger()
  in visual_display_manager.py to match project logging conventions
- Eliminate duplicate public/private weather draw methods — public draw_sun/
  draw_cloud/draw_rain/draw_snow now delegate to the private _draw_* variants
  so plugins get consistent pixel output in tests vs production
- Default install_deps=False in dev_server.py and render_plugin.py — dev
  scripts don't need to run pip install; developers are expected to have
  plugin deps installed in their venv already
- Guard plugins_dir fixture against PermissionError during directory iteration
- Fix PluginInstallManager.updateAll() to fall back to window.installedPlugins
  when PluginStateManager.installedPlugins is empty (plugins_manager.js
  populates window.installedPlugins independently of PluginStateManager)
- Remove 5 debug console.log statements from plugins_manager.js button setup
  and initialization code

* fix(scroll): fix scroll completion to prevent multi-pass wrapping

Change required_total_distance from total_scroll_width + display_width to
total_scroll_width alone. The scrolling image already contains display_width
pixels of blank initial padding, so reaching total_scroll_width means all
content has scrolled off-screen. The extra display_width term was causing
1-2+ unnecessary wrap-arounds, making the same games appear multiple times
and producing a black flicker between passes.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(dev-preview): address PR #264 code review findings

- docs/DEV_PREVIEW.md: add bash language tag to fenced code block
- scripts/dev_server.py: add MAX/MIN_WIDTH/HEIGHT constants and validate
  width/height in render endpoint; add structured logger calls to
  discover_plugins (missing dirs, hidden entries, missing manifest,
  JSON/OS errors, duplicate ids); add type annotations to all helpers
- scripts/render_plugin.py: add MIN/MAX_DIMENSION validation after
  parse_args; replace prints with get_logger() calls; narrow broad
  Exception catches to ImportError/OSError/ValueError in plugin load
  block; add type annotations to all helpers and main(); rename unused
  module binding to _module
- scripts/run_plugin_tests.py: wrap plugins_path.iterdir() in
  try/except PermissionError with fallback to plugin-repos/
- scripts/templates/dev_preview.html: replace non-focusable div toggles
  with button role="switch" + aria-checked; add keyboard handlers
  (Enter/Space); sync aria-checked in toggleGrid/toggleAutoRefresh
- src/common/scroll_helper.py: early-guard zero total_scroll_width to
  keep scroll_position at 0 and skip completion/wrap logic
- src/plugin_system/testing/visual_display_manager.py: forward color
  arg in draw_cloud -> _draw_cloud; add color param to _draw_cloud;
  restore _scrolling_state in reset(); narrow broad Exception catches in
  _load_fonts to FileNotFoundError/OSError/ImportError; add explicit
  type annotations to draw_text
- test/plugins/test_visual_rendering.py: use context manager for
  Image.open in test_save_snapshot
- test/plugins/conftest.py: add return type hints to all fixtures

ChuckandChuck 7d71656cf1 Plugins (#145) 
Chaotic mega-merge into main. THINGS WILL PROBABLY BE BROKEN


* chore: Update soccer-scoreboard submodule to merged commit

- Update submodule reference to include manifest.json v2 registry format
- Version updated to 1.0.1

* refactor: Remove test_mode and logo_dir config reading from base SportsCore

- Remove test_mode initialization and usage
- Remove logo_dir reading from mode_config
- Use LogoDownloader defaults directly for logo directories

* chore: Update plugin submodules after removing global properties

- Update basketball-scoreboard submodule (removed global test_mode, live_priority, dynamic_duration, logo_dir)
- Update soccer-scoreboard submodule (removed global test_mode, live_priority, dynamic_duration, logo_dir)

* feat(calendar): Add credentials.json file upload via web interface

- Add API endpoint /api/v3/plugins/calendar/upload-credentials for file upload
- Validate JSON format and Google OAuth structure
- Save file to plugin directory with secure permissions (0o600)
- Backup existing credentials.json before overwriting
- Add file upload widget support for string fields in config forms
- Add frontend handler handleCredentialsUpload() for single file uploads
- Update .gitignore to allow calendar submodule
- Update calendar submodule reference

* fix(web): Improve spacing for nested configuration sections

- Add dynamic margin based on nesting depth (mb-6 for deeply nested sections)
- Increase padding in nested content areas (py-3 to py-4)
- Add extra spacing after nested sections to prevent overlap
- Enhance CSS spacing for nested sections (1.5rem for nested, 2rem for deeply nested)
- Add padding-bottom to expanded nested content to prevent cutoff
- Fixes issue where game_limits and other nested settings were hidden under next section header

* chore(plugins): Update sports scoreboard plugins with live update interval fix

- Updated hockey-scoreboard, football-scoreboard, basketball-scoreboard, and soccer-scoreboard submodules
- All plugins now fix the interval selection bug that caused live games to update every 5 minutes instead of 30 seconds
- Ensures all live games update at the configured live_update_interval (30s) for timely score updates

* fix: Initialize test_mode in SportsLive and fix config migration

- Add test_mode initialization in SportsLive.__init__() to prevent AttributeError
- Remove invalid new_secrets parameter from save_config_atomic() call in config migration
- Fixes errors: 'NBALiveManager' object has no attribute 'test_mode'
- Fixes errors: ConfigManager.save_config_atomic() got unexpected keyword argument 'new_secrets'

* chore: Update submodules with test_mode initialization fixes

- Update basketball-scoreboard submodule
- Update soccer-scoreboard submodule

* fix(plugins): Auto-stash local changes before plugin updates

- Automatically stash uncommitted changes before git pull during plugin updates
- Prevents update failures when plugins have local modifications
- Improves error messages for git update failures
- Matches behavior of main LEDMatrix update process

* fix(basketball-scoreboard): Update submodule with timeout fix

- Updated basketball-scoreboard plugin to fix update() timeout issue
- Plugin now uses fire-and-forget odds fetching for upcoming games
- Prevents 30-second timeout when processing many upcoming games

Also fixed permission issue on devpi:
- Changed /var/cache/ledmatrix/display_on_demand_state.json permissions
  from 600 to 660 to allow web service (devpi user) to read the file

* fix(cache): Ensure cache files use 660 permissions for group access

- Updated setup_cache.sh to set file permissions to 660 (not 775)
- Updated first_time_install.sh to properly set cache file permissions
- Modified DiskCache to set 660 permissions when creating cache files
- Ensures display_on_demand_state.json and other cache files are readable
  by web service (devpi user) which is in ledmatrix group

This fixes permission issues where cache files were created with 600
permissions, preventing the web service from reading them. Now files
are created with 660 (rw-rw----) allowing group read access.

* fix(soccer-scoreboard): Update submodule with manifest fix

- Updated soccer-scoreboard plugin submodule
- Added missing entry_point and class_name to manifest.json
- Fixes plugin loading error: 'No class_name in manifest'

Also fixed cache file permissions on devpi server:
- Changed display_on_demand_state.json from 600 to 660 permissions
- Allows web service (devpi user) to read cache files

* fix(display): Remove update_display() calls from clear() to prevent black flash

Previously, display_manager.clear() was calling update_display() twice,
which immediately showed a black screen on the hardware before new
content could be drawn. This caused visible black flashes when switching
between modes, especially when plugins switch from general modes (e.g.,
football_upcoming) to specific sub-modes (e.g., nfl_upcoming).

Now clear() only prepares the buffer without updating the hardware.
Callers can decide when to update the display, allowing smooth transitions
from clear → draw → update_display() without intermediate black flashes.

Places that intentionally show a cleared screen (error cases) already
explicitly call update_display() after clear(), so backward compatibility
is maintained.

* fix(scroll): Prevent wrap-around before cycle completion in dynamic duration

- Check scroll completion BEFORE allowing wrap-around
- Clamp scroll_position when complete to prevent visual loop
- Only wrap-around if cycle is not complete yet
- Fixes issue where stocks plugin showed first stock again at end
- Completion logged only once to avoid spam
- Ensures smooth transition to next mode without visual repeat

* fix(on-demand): Ensure on-demand buttons work and display service runs correctly

- Add early stub functions for on-demand modal to ensure availability when Alpine.js initializes
- Increase on-demand request cache max_age from 5min to 1hr to prevent premature expiration
- Fixes issue where on-demand buttons were not functional due to timing issues
- Ensures display service properly picks up on-demand requests when started

* test: Add comprehensive test coverage (30%+)

- Add 100+ new tests across core components
- Add tests for LayoutManager (27 tests)
- Add tests for PluginLoader (14 tests)
- Add tests for SchemaManager (20 tests)
- Add tests for MemoryCache and DiskCache (24 tests)
- Add tests for TextHelper (9 tests)
- Expand error handling tests (7 new tests)

* test(web): Add comprehensive API endpoint tests

- Add 30 new tests for Flask API endpoints in test/test_web_api.py
- Cover config, system, display, plugins, fonts, and error handling APIs
- Increase test coverage from 30.26% to 30.87%
- All 267 tests passing

Tests cover:
- Config API: GET/POST main config, schedule, secrets
- System API: Status, version, system actions
- Display API: Current display, on-demand start/stop

- Fonts API: Catalog, tokens, overrides
- Error handling: Invalid JSON, missing fields, 404s

* test(plugins): Add comprehensive integration tests for all plugins

- Add base test class for plugin integration tests
- Create integration tests for all 6 plugins:
  - basketball-scoreboard (11 tests)
  - calendar (10 tests)
  - clock-simple (11 tests)
  - odds-ticker (9 tests)

- All 331 tests passing

Tests verify:
- Plugin loading and instantiation
- Required methods (update, display)
- Manifest validation
- Display modes
- Config schema validation
- Graceful handling of missing API credentials

Uses hybrid approach: integration tests in main repo,
plugin-specific unit tests remain in plugin submodules.

* Add mqtt-notifications plugin as submodule

* fix(sports): Respect games_to_show settings for favorite teams

- Fix upcoming games to show N games per team (not just 1)
- Fix recent games to show N games per team (not just 1)

- Remove debug instrumentation that was causing ERR_BLOCKED_BY_CLIENT errors

* fix: Prevent unnecessary plugin tab redraws

- Add check to only update tabs when plugin list actually changes
- Increase debounce timeout to batch rapid changes
- Compare plugin IDs before updating to avoid redundant redraws
- Fix setter to check for actual changes before triggering updates

* fix: Prevent form-groups from sliding out of view when nested sections expand

- Increase margin-bottom on nested-sections for better spacing
- Add clear: both to nested-sections to ensure proper document flow
- Change overflow to visible when expanded to allow natural flow
- Add margin-bottom to expanded content
- Add spacing rules for form-groups that follow nested sections
- Add clear spacer div after nested sections

* fix: Reduce excessive debug logging in generateConfigForm

- Only log once per plugin instead of on every function call
- Prevents log spam when Alpine.js re-renders the form multiple times
- Reduces console noise from 10+ logs per plugin to 1 log per plugin

* fix: Prevent nested section content from sliding out of view when expanded

- Remove overflow-hidden from nested-section in base.html (was causing clipping)
- Add scrollIntoView to scroll expanded sections into view within modal
- Set nested-section overflow to visible to prevent content clipping
- Add min-height to nested-content to ensure proper rendering
- Wait for animation to complete before scrolling into view

* fix: Prevent form-groups from overlapping and appearing outside view

- Change nested-section overflow to hidden by default, visible when expanded
- Add :has() selector to allow overflow when content is expanded
- Ensure form-groups after nested sections have proper spacing and positioning
- Add clear: both and width: 100% to prevent overlap
- Use !important for margin-top to ensure spacing is applied
- Ensure form-groups are in normal document flow with float: none

* fix: Use JavaScript to toggle overflow instead of :has() selector

- :has() selector may not be supported in all browsers
- Use JavaScript to set overflow: visible when expanded, hidden when collapsed
- This ensures better browser compatibility while maintaining functionality

* fix: Make parent sections expand when nested sections expand

- Add updateParentNestedContentHeight() helper to recursively update parent heights
- When a nested section expands, recalculate all parent nested-content max-heights
- Ensures parent sections (like NFL) expand to accommodate expanded child sections
- Updates parent heights both on expand and collapse for proper animation

* refactor: Simplify parent section expansion using CSS max-height: none

- Remove complex recursive parent height update function
- Use CSS max-height: none when expanded to allow natural expansion
- Parent sections automatically expand because nested-content has no height constraint
- Simpler and more maintainable solution

* refactor: Remove complex recursive parent height update function

- CSS max-height: none already handles parent expansion automatically
- No need for JavaScript to manually update parent heights
- Much simpler and cleaner solution

* debug: Add instrumentation to debug auto-collapse issue

- Add logging to track toggle calls and state changes
- Add guard to prevent multiple simultaneous toggles
- Pass event object to prevent bubbling
- Improve state detection logic
- Add return false to onclick handlers

* chore: Remove debug instrumentation from toggleNestedSection

- Keep functional fixes: event handling, toggle guard, improved state detection
- Code is now clean and production-ready

* fix(web): Add browser refresh note to plugin fetch errors

* refactor(text-display): Update submodule to use ScrollHelper

* fix(text-display): Fix scrolling display issue - update position in display()

* feat(text-display): Add scroll_loop option and improve scroll speed control

* debug: Add instrumentation to track plugin enabled state changes

Added debug logging to investigate why plugins appear to disable themselves:
- Track enabled state during plugin load (before/after schema merge)
- Track enabled state during plugin reload
- Track enabled state preservation during config save
- Track state reconciliation fixes
- Track enabled state updates in on_config_change

This will help identify which code path is causing plugins to disable.

* debug: Fix debug log path to work on Pi

Changed hardcoded log path to use dynamic project root detection:
- Uses LEDMATRIX_ROOT env var if set
- Falls back to detecting project root by looking for config directory
- Creates .cursor directory if it doesn't exist
- Falls back to /tmp/ledmatrix_debug.log if all else fails
- Added better error handling with logger fallback

* Remove debug instrumentation for plugin enabled state tracking

Removed all debug logging that was added to track plugin enabled state changes.
The instrumentation has been removed as requested.

* Reorganize documentation and cleanup test files

- Move documentation files to docs/ directory
- Remove obsolete test files
- Update .gitignore and README

* feat(text-display): Switch to frame-based scrolling with high FPS support

* fix(text-display): Add backward compatibility for ScrollHelper sub-pixel scrolling

* feat(scroll_helper): Add sub-pixel scrolling support for smooth movement

- Add sub-pixel interpolation using scipy (if available) or numpy fallback
- Add set_sub_pixel_scrolling() method to enable/disable feature
- Implement _get_visible_portion_subpixel() for fractional pixel positioning
- Implement _interpolate_subpixel() for linear interpolation
- Prevents pixel skipping at slow scroll speeds
- Maintains backward compatibility with integer pixel path

* fix(scroll_helper): Reset last_update_time in reset_scroll() to prevent jump-ahead

- Reset last_update_time when resetting scroll position
- Prevents large delta_time on next update after reset
- Fixes issue where scroll would immediately complete again after reset
- Ensures smooth scrolling continuation after loop reset

* fix(scroll_helper): Fix numpy broadcasting error in sub-pixel interpolation

- Add output_width parameter to _interpolate_subpixel() for variable widths
- Fix wrap-around case to use correct widths for interpolation
- Handle edge cases where source array is smaller than expected
- Prevent 'could not broadcast input array' errors in sub-pixel scrolling
- Ensure proper width matching in all interpolation paths

* feat(scroll): Add frame-based scrolling mode for smooth LED matrix movement

- Add frame_based_scrolling flag to ScrollHelper
- When enabled, moves fixed pixels per step, throttled by scroll_delay
- Eliminates time-based jitter by ignoring frame timing variations
- Provides stock-ticker-like smooth, predictable scrolling
- Update text-display plugin to use frame-based mode

This addresses stuttering issues where time-based scrolling caused
visual jitter due to frame timing variations in the main display loop.

* fix(scroll): Fix NumPy broadcasting errors in sub-pixel wrap-around

- Ensure _interpolate_subpixel always returns exactly requested width
- Handle cases where scipy.ndimage.shift produces smaller arrays
- Add padding logic for wrap-around cases when arrays are smaller than expected
- Prevents 'could not broadcast input array' errors during scrolling

* refactor(scroll): Remove sub-pixel interpolation, use high FPS integer scrolling

- Disable sub-pixel scrolling by default in ScrollHelper
- Simplify get_visible_portion to always use integer pixel positioning
- Restore frame-based scrolling logic for smooth high FPS movement
- Use high frame rate (like stock ticker) for smoothness instead of interpolation
- Reduces complexity and eliminates broadcasting errors

* fix(scroll): Prevent large pixel jumps in frame-based scrolling

- Initialize last_step_time properly to prevent huge initial jumps
- Clamp scroll_speed to max 5 pixels/frame in frame-based mode
- Prevents 60-pixel jumps when scroll_speed is misconfigured
- Simplified step calculation to avoid lag catch-up jumps

* fix(text-display): Align config schema and add validation

- Update submodule reference
- Adds warning and logging for scroll_speed config issues

* fix(scroll): Simplify frame-based scrolling to match stock ticker behavior

- Remove throttling logic from frame-based scrolling
- Move pixels every call (DisplayController's loop timing controls rate)
- Add enable_scrolling attribute to text-display plugin for high-FPS treatment
- Matches stock ticker: simple, predictable movement every frame
- Eliminates jitter from timing mismatches between DisplayController and ScrollHelper

- Restore time-based throttling using scroll_delay
- Move pixels only when scroll_delay has passed
- Handle lag catch-up with reasonable caps to prevent huge jumps
- Preserve fractional timing for smooth operation
- Now scroll_delay actually controls the scroll speed as intended

* feat(text-display): Add FPS counter logging

- Update submodule reference
- Adds FPS tracking and logging every 5 seconds

* fix(text-display): Add display-width buffer so text scrolls completely off

- Update submodule reference
- Adds end buffer to ensure text exits viewport before looping

* fix: Prevent premature game switching in SportsLive

- Set last_game_switch when games load even if current_game already exists
- Set last_game_switch when same games update but it's still 0
- Add guard to prevent switching check when last_game_switch is 0
- Fixes issue where first game shows for only ~2 seconds before switching
- Also fixes random screen flickering when games change prematurely

* feat(plugins): Add branch selection support for plugin installation

- Add optional branch parameter to install_plugin() and install_from_url() in store_manager
- Update API endpoints to accept and pass branch parameter

- Each plugin can now have its own branch specified independently

* debug: Add logging to _should_exit_dynamic

* feat(display_controller): Add universal get_cycle_duration support for all plugins

UNIVERSAL FEATURE: Any plugin can now implement get_cycle_duration() to dynamically
calculate the total time needed to show all content for a mode.

New method:
- _plugin_cycle_duration(plugin, display_mode): Queries plugin for calculated duration

Integration:
- Display controller calls plugin.get_cycle_duration(display_mode)
- Uses returned duration as target (respecting max cap)
- Falls back to cap if not provided

Benefits:
- Football plugin: Show all games (3 games × 15s = 45s total)
- Basketball plugin: Could implement same logic
- Hockey/Baseball/any sport: Universal support
- Stock ticker: Could calculate based on number of stocks
- Weather: Could calculate based on forecast days

Example plugin implementation:

Result: Plugins control their own display duration based on actual content,
creating a smooth user experience where all content is shown before switching.

* debug: Add logging to cycle duration call

* debug: Change loop exit logs to INFO level

* fix: Change cycle duration logs to INFO level

* fix: Don't exit loop on False for dynamic duration plugins

For plugins with dynamic duration enabled, keep the display loop running
even when display() returns False. This allows games to continue rotating
within the calculated duration.

The loop will only exit when:
- Cycle is complete (plugin reports all content shown)
- Max duration is reached
- Mode is changed externally

* fix(schedule): Improve display scheduling functionality

- Add GET endpoint for schedule configuration retrieval
- Fix mode switching to clean up old config keys (days/start_time/end_time)
- Improve error handling with consistent error_response() usage
- Enhance display controller schedule checking with better edge case handling
- Add validation for time formats and ensure at least one day enabled in per-day mode
- Add debug logging for schedule state changes

Fixes issues where schedule mode switching left stale config causing incorrect behavior.

* fix(install): Add cmake and ninja-build to system dependencies

Resolves h3 package build failure during first-time installation.
The h3 package (dependency of timezonefinder) requires CMake and
Ninja to build from source. Adding these build tools ensures
successful installation of all Python dependencies.

* fix: Pass display_mode in ALL loop calls to maintain sticky manager

CRITICAL FIX: Display controller was only passing display_mode on first call,
causing plugins to fall back to internal mode cycling and bypass sticky
manager logic.

Now consistently passes display_mode=active_mode on every display() call in
both high-FPS and normal loops. This ensures plugins maintain mode context
and sticky manager state throughout the entire display duration.

* feat(install): Add OS check for Raspberry Pi OS Lite (Trixie)

- Verify OS is Raspberry Pi OS (raspbian/debian)
- Require Debian 13 (Trixie) specifically
- Check for Lite version (no desktop environment)
- Exit with clear error message if requirements not met
- Provide instructions for obtaining correct OS version

* fix(web-ui): Add missing notification handlers to quick action buttons

- Added hx-on:htmx:after-request handlers to all quick action buttons in overview.html
- Added hx-ext='json-enc' for proper JSON encoding
- Added missing notification handler for reboot button in index.html
- Users will now see toast notifications when actions complete or fail

* fix(display): Ensure consistent display mode handling in all plugin calls

- Updated display controller to consistently pass display_mode in all plugin display() calls.
- This change maintains the sticky manager state and ensures plugins retain their mode context throughout the display duration.
- Addresses issues with mode cycling and improves overall display reliability.

* fix(display): Enhance display mode persistence across plugin updates

- Updated display controller to ensure display_mode is consistently maintained during plugin updates.
- This change prevents unintended mode resets and improves the reliability of display transitions.

- Add checkbox-group widget rendering in plugins_manager.js
- Update form processing to handle checkbox groups with [] naming
- Support for friendly labels via x-options in config schemas
- Update odds-ticker submodule with checkbox-group implementation

* fix(plugins): Preserve enabled state when saving plugin config from main config endpoint

When saving plugin configuration through save_main_config endpoint, the enabled
field was not preserved if missing from the form data. This caused plugins to
be automatically disabled when users saved their configuration from the plugin
manager tab.

This fix adds the same enabled state preservation logic that exists in
save_plugin_config endpoint, ensuring consistent behavior across both endpoints.
The enabled state is preserved from current config, plugin instance, or defaults
to True to prevent unexpected disabling of plugins.

* fix(git): Resolve git status timeout and exclude plugins from base project updates

- Add --untracked-files=no flag to git status for faster execution
- Increase timeout from 5s to 30s for git status operations
- Add timeout exception handling for git status and stash operations

* fix(scroll): Correct dynamic duration calculation for frame-based scrolling

- Fix calculate_dynamic_duration() to properly handle frame-based scrolling mode
- Convert scroll_speed from pixels/frame to pixels/second when in frame-based mode
- Prevents incorrect duration calculations (e.g., 2609s instead of 52s)
- Affects all plugins using ScrollHelper: odds-ticker, leaderboard, stocks, text-display
- Add debug logging to show scroll mode and effective speed

* Remove version logic from plugin system, use git commits instead

- Remove version parameter from install_plugin() method
- Rename fetch_latest_versions to fetch_commit_info throughout codebase

- Update .gitignore to ignore all plugin folders (remove whitelist exceptions)
- Remove plugin directories from git index (plugins now installed via plugin store only)

Plugins now always install latest commit from default branch. Version fields
replaced with git commit SHA and commit dates. System uses git-based approach
for all plugin metadata.

* feat(plugins): Normalize all plugins as git submodules

- Convert all 18 plugins to git submodules for uniform management
- Add submodules for: baseball-scoreboard, christmas-countdown, football-scoreboard, hockey-scoreboard, ledmatrix-flights, ledmatrix-leaderboard, ledmatrix-music, ledmatrix-stocks, ledmatrix-weather, static-image
- Re-initialize mqtt-notifications as proper submodule
- Update .gitignore to allow all plugin submodules

- Fix shell scripts in scripts/ to correctly resolve project root (go up one more level)
- Fix scripts in scripts/fix_perms/ to correctly resolve project root
- Update diagnose_web_interface.sh to reference moved start_web_conditionally.py path

All scripts now correctly determine project root after reorganization.

* fix(install): Update first_time_install.sh to detect and update service files with old paths

- Check for old paths in service files and reinstall if needed
- Always reinstall main service (install_service.sh is idempotent)
- This ensures existing installations get updated paths after reorganization

- Replace Alpine.js x-for template with manual DOM manipulation
- Add updateSelectOptions() method to directly update select dropdown
- This fixes issue where networks weren't appearing in dropdown
- Alpine.js x-for inside select elements can be unreliable

* feat(web-ui): Add patternProperties support for dynamic key-value pairs

- Add UI support for patternProperties objects (custom_feeds, feed_logo_map)
- Implement key-value pair editor with add/remove functionality
- Add JavaScript functions for managing dynamic key-value pairs
- Update form submission to handle patternProperties JSON data
- Enable easy configuration of feed_logo_map in web UI

* chore: Update ledmatrix-news submodule to latest commit

* fix(plugins): Handle arrays of objects in config normalization

Fix configuration validation failure for static-image plugin by adding
recursive normalization support for arrays of objects. The normalize_config_values
function now properly handles arrays containing objects (like image_config.images)
by recursively normalizing each object in the array using the items schema properties.

This resolves the 'configuration validation failed' error when saving static
image plugin configuration with multiple images.

* fix(plugins): Handle union types in config normalization and form generation

Fix configuration validation for fields with union types like ['integer', 'null'].
The normalization function now properly handles:
- Union types in top-level fields (e.g., random_seed: ['integer', 'null'])
- Union types in array items
- Empty string to None conversion for nullable fields
- Form generation and submission for union types

This resolves validation errors when saving plugin configs with nullable
integer/number fields (e.g., rotation_settings.random_seed in static-image plugin).

Also improves UX by:
- Adding placeholder text for nullable fields explaining empty = use default
- Properly handling empty values in form submission for union types

* fix(plugins): Improve union type normalization with better edge case handling

Enhanced normalization for union types like ['integer', 'null']:
- Better handling of whitespace in string values
- More robust empty string to None conversion
- Fallback to None when conversion fails and null is allowed
- Added debug logging for troubleshooting normalization issues
- Improved handling of nested object fields with union types

This should resolve remaining validation errors for nullable integer/number
fields in nested objects (e.g., rotation_settings.random_seed).

* chore: Add ledmatrix-news plugin to .gitignore exceptions

* Fix web interface service script path in install_service.sh

- Updated ExecStart path from start_web_conditionally.py to scripts/utils/start_web_conditionally.py
- Updated diagnose_web_ui.sh to check for correct script path
- Fixes issue where web UI service fails to start due to incorrect script path

* Fix nested configuration section headers not expanding

Fixed toggleNestedSection function to properly calculate scrollHeight when
expanding nested configuration sections. The issue occurred when sections
started with display:none - the scrollHeight was being measured before the
browser had a chance to lay out the element, resulting in a value of 0.

Changes:
- Added setTimeout to delay scrollHeight measurement until after layout
- Added overflow handling during animations to prevent content jumping
- Added fallback for edge cases where scrollHeight might still be 0
- Set maxHeight to 'none' after expansion completes for natural growth
- Updated function in both base.html and plugins_manager.js

This fix applies to all plugins with nested configuration sections, including:
- Hockey/Football/Basketball/Baseball/Soccer scoreboards (customization, global sections)
- All plugins with transition, display, and other nested configuration objects

Fixes configuration header expansion issues across all plugins.

* Fix syntax error in first_time_install.sh step 8.5

Added missing 'fi' statement to close the if block in the WiFi monitor

especially when connected via Ethernet, making it impossible to enable
WiFi from the web UI.

* fix(plugin-templates): Fix unreachable fallback to expired cache in update() method

The exception handler in update() checked the cached variable, which would
always be None or falsy at that point. If fresh cached data existed, the
method returned early. If cached data was expired, it was filtered out by
max_age constraint. The fix retrieves cached data again in the exception
handler with a very large max_age (1 year) to effectively bypass expiration
check and allow fallback to expired data when fetch fails.

* fix(plugin-templates): Resolve plugin_id mismatch in test template setUp method

* feat(plugins): Standardize manifest version fields schema

- Consolidate version fields to use consistent naming:

* chore: Add GitHub sponsor button configuration

* fix(wifi): Fix aggressive AP mode enabling and improve WiFi detection

Critical fixes:
- Change auto_enable_ap_mode default from True to False (manual enable only)
- Fixes issue where Pi would disconnect from network after code updates
- Matches documented behavior (was incorrectly defaulting to True in code)

Improvements:
- Add grace period: require 3 consecutive disconnected checks (90s) before enabling AP mode
- Prevents AP mode from enabling on transient network hiccups
- Improve WiFi status detection with retry logic and better nmcli parsing
- Enhanced logging for debugging WiFi connection issues
- Better handling of WiFi device detection (works with any wlan device)

This prevents the WiFi monitor from aggressively enabling AP mode and
disconnecting the Pi from the network when there are brief network issues
or during system initialization.

* fix(wifi): Revert auto_enable_ap_mode default to True with grace period protection

Change default back to True for auto_enable_ap_mode while keeping the grace
period protection that prevents interrupting valid WiFi connections.

- Default auto_enable_ap_mode back to True (useful for setup scenarios)
- Grace period (3 consecutive checks = 90s) prevents false positives
- Improved WiFi detection with retry logic ensures accurate status
- AP mode will auto-enable when truly disconnected, but won't interrupt
  valid connections due to transient detection issues

* fix(news): Update submodule reference for manifest fix

Update ledmatrix-news submodule to include the fixed manifest.json with
required entry_point and class_name fields.

AP Mode Changes:
- Remove password requirement from AP mode (open network for easier setup)
- Update hostapd config to create open network (no WPA/WPA2)
- Update nmcli hotspot to create open network (no password parameter)

WiFi Page Loading Fixes:
- Download local copies of HTMX and Alpine.js libraries
- Auto-detect AP mode (192.168.4.x) and use local JS files instead of CDN
- Auto-open WiFi tab when accessing via AP mode IP
- Add fallback loading if HTMX fails to load
- Ensures WiFi setup page works in AP mode without internet access

This fixes the issue where the WiFi page wouldn't load on iPhone when
accessing via AP mode (192.168.4.1:5000) because CDN resources couldn't
be fetched without internet connectivity.

* feat(wifi): Add explicit network switching support with clean disconnection

WiFi Manager Improvements:
- Explicitly disconnect from current network before connecting to a new one
- Add skip_ap_check parameter to disconnect_from_network() to prevent AP mode
  from activating during network switches
- Check if already connected to target network to avoid unnecessary work
- Improved logging for network switching operations

Web UI Improvements:
- Detect and display network switching status in UI
- Show 'Switching from [old] to [new]...' message when switching networks
- Enhanced status reloading after connection (multiple checks at 2s, 5s, 10s)
- Better user feedback during network transitions

This ensures clean network switching without AP mode interruptions and
provides clear feedback to users when changing WiFi networks.

* fix(web-ui): Add fallback content loading when HTMX fails to load

Problem:
- After recent updates, web UI showed navigation and CPU status but main
  content tabs never loaded
- Content tabs depend on HTMX's 'revealed' trigger to load
- If HTMX failed to load or initialize, content would never appear

Solutions:
- Enhanced HTMX loading verification with timeout checks
- Added fallback direct fetch for overview tab if HTMX fails
- Added automatic tab content loading when tabs change
- Added loadTabContent() method to manually trigger content loading
- Added global 'htmx-load-failed' event for error handling
- Automatic retry after 5 seconds if HTMX isn't available
- Better error messages and console logging for debugging

This ensures the web UI loads content even if HTMX has issues,
providing graceful degradation and better user experience.

* feat(web-ui): Add support for plugin custom HTML widgets and static file serving

- Add x-widget: custom-html support in config schema generation
- Add loadCustomHtmlWidget() function to load HTML from plugin directories
- Add /api/v3/plugins/<plugin_id>/static/<file_path> endpoint for serving plugin static files
- Enhance execute_plugin_action() to pass params via stdin as JSON for scripts
- Add JSON output parsing for script action responses

These changes enable plugins to provide custom UI components while keeping
all functionality plugin-scoped. Used by of-the-day plugin for file management.

- Move OAuth flow check before script execution in else block
- Remove unreachable code that was causing syntax error
- OAuth check now happens first, then falls back to script execution
- Resolves SyntaxError at line 3458

* fix(web-ui): Define app() function in head for Alpine.js initialization

- Define minimal app() function in head before Alpine.js loads
- Ensures app() is available when Alpine initializes
- Full implementation in body enhances/replaces the stub
- Fixes 'app is not defined' and 'activeTab is not defined' errors

- Display category metadata (display name, data file path)
- Used by of-the-day plugin for category management

* fix(wifi): Ensure AP mode hotspot is always open (no password)

Problem:
- LEDMatrix-Setup WiFi AP was still asking for password despite code changes
- Existing hotspot connections with passwords weren't being fully cleaned up
- NetworkManager might reuse old connection profiles with passwords

Solutions:
- More thorough cleanup: Delete all hotspot-related connections, not just known names
- Verification: Check if hotspot has password after creation
- Automatic fix: Remove password and restart connection if security is detected
- Better logging: Log when password is detected and removed

This ensures the AP mode hotspot is always open for easy setup access,
even if there were previously saved connections with passwords.

* fix(wifi): Improve network switching reliability and device state handling

Problem:
- Pi failing to switch WiFi networks via web UI
- Connection attempts happening before device is ready
- Disconnect not fully completing before new connection attempt
- Connection name lookup issues when SSID doesn't match connection name

Solutions:
- Improved disconnect logic: Disconnect specific connection first, then device
- Device state verification: Wait for device to be ready (disconnected/unavailable) before connecting
- Better connection lookup: Search by SSID, not just connection name
- Increased wait times: 2 seconds for disconnect to complete
- State checking before activating existing connections
- Enhanced error handling and logging throughout

This ensures network switching works reliably by properly managing device
state transitions and using correct connection identifiers.

- Stub's updatePluginTabs was empty, preventing tabs from showing
- Add basic implementation that creates plugin tabs in navigation bar
- Ensures plugin tabs appear immediately when plugins load, even before full implementation merges
- Fixes issue where plugin navigation bar wasn't working

* feat(api): Populate uploaded_files and categories from disk for of-the-day plugin

- Scan of_the_day directory for existing JSON files when loading config
- Populate uploaded_files array from files on disk
- Populate categories from files on disk if not in config
- Categories default to disabled, user can enable them
- Ensures existing JSON files (word_of_the_day.json, slovenian_word_of_the_day.json) appear in UI

* fix(api): Improve category merging logic for of-the-day plugin

- Preserve existing category enabled state when merging with files from disk
- Ensure all JSON files from disk appear in categories section
- Categories from files default to disabled, preserving user choices
- Properly merge existing config with scanned files

* fix(wifi): More aggressive password removal for AP mode hotspot

Problem:
- LEDMatrix-Setup network still asking for password despite previous fixes
- NetworkManager may add default security settings to hotspots
- Existing connections with passwords may not be fully cleaned up

Solutions:
- Always remove ALL security settings after creating hotspot (not just when detected)
- Remove multiple security settings: key-mgmt, psk, wep-key, auth-alg
- Verify security was removed and recreate connection if verification fails
- Improved cleanup: Delete connections by SSID match, not just by name
- Disconnect connections before deleting them
- Always restart connection after removing security to apply changes
- Better logging for debugging

This ensures the AP mode hotspot is always open, even if NetworkManager
tries to add default security settings.

* perf(web): Optimize web interface performance and fix JavaScript errors

All animations now GPU-accelerated (transform/opacity only).
Optimized for low-powered Raspberry Pi devices.

* fix(web): Resolve ReferenceError for getInstalledPluginsSafe in v3 stub initialization

Move getInstalledPluginsSafe() function definition before the app() stub code that uses it. The function was previously defined at line 3756 but was being called at line 849 during Alpine.js initialization, causing a ReferenceError when loadInstalledPluginsDirectly() attempted to load plugins before the full implementation was ready.

* fix(web): Resolve TypeError for installedPlugins.map in plugin loading

Fix PluginAPI.getInstalledPlugins() to properly extract plugins array from API response structure. The API returns {status: 'success', data: {plugins: [...]}}, but the method was returning response.data (the object) instead of response.data.plugins (the array).

Changes:
- api_client.js: Extract plugins array from response.data.plugins
- plugins_manager.js: Add defensive array checks and handle array return value correctly
- base.html: Add defensive check in getInstalledPluginsSafe() to ensure plugins is always an array

This prevents 'installedPlugins.map is not a function' errors when loading plugins.

* style(web-ui): Enhance navigation bar styling for better readability

- Improve contrast: Change inactive tab text from gray-500 to gray-700
- Add gradient background and thicker border for active tabs
- Enhance hover states with background highlights
- Add smooth transitions using GPU-accelerated properties
- Update all navigation buttons (system tabs and plugin tabs)
- Add updatePluginTabStates() method for dynamic tab state management

All changes are CSS-only with zero performance overhead.

* fix(web-ui): Optimize plugin loading and reduce initialization errors

- Make generateConfigForm accessible to inline Alpine components via parent scope
- Consolidate plugin initialization to prevent duplicate API calls
- Fix script execution from HTMX-loaded content by extracting scripts before DOM insertion
- Add request deduplication to loadInstalledPlugins() to prevent concurrent requests
- Improve Alpine component initialization with proper guards and fallbacks

This eliminates 'generateConfigForm is not defined' errors and reduces plugin
API calls from 3-4 duplicate calls to 1 per page load, significantly improving
page load performance.

* fix(web-ui): Add guard check for generateConfigForm to prevent Alpine errors

Add typeof check in x-show to prevent Alpine from evaluating generateConfigForm
before the component methods are fully initialized. This eliminates the
'generateConfigForm is not defined' error that was occurring during component
initialization.

* fix(web-ui): Fix try-catch block structure in script execution code

Correct the nesting of try-catch block inside the if statement for script execution.
The catch block was incorrectly placed after the else clause, causing a syntax error.

* fix(web-ui): Escape quotes in querySelector to avoid HTML attribute conflicts

Change double quotes to single quotes in the CSS selector to prevent conflicts
with HTML attribute parsing when the x-data expression is embedded.

* style(web): Improve button text readability in Quick Actions section

* fix(web): Resolve Alpine.js expression errors in plugin configuration component

- Capture plugin from parent scope into component data to fix parsing errors
- Update all plugin references to use this.plugin in component methods
- Fix x-init to properly call loadPluginConfig method
- Resolves 'Uncaught ReferenceError' for isOnDemandLoading, onDemandLastUpdated, and other component properties

* fix(web): Fix remaining Alpine.js scope issues in plugin configuration

- Use this.generateConfigForm in typeof checks and method calls
- Fix form submission to use this.plugin.id
- Use $root. prefix for parent scope function calls (refreshPlugin, updatePlugin, etc.)
- Fix confirm dialog string interpolation
- Ensures all component methods and properties are properly scoped

* fix(web): Add this. prefix to all Alpine.js component property references

- Fix all template expressions to use this. prefix for component properties
- Update isOnDemandLoading, onDemandLastUpdated, onDemandRefreshing references
- Update onDemandStatusClass, onDemandStatusText, onDemandServiceClass, onDemandServiceText
- Update disableRunButton, canStopOnDemand, showEnableHint, loading references
- Ensures Alpine.js can properly resolve all component getters and properties

* fix(web): Resolve Alpine.js expression errors in plugin configuration

- Move complex x-data object to pluginConfigData() function for better parsing
- Fix all template expressions to use this.plugin instead of plugin
- Add this. prefix to all method calls in event handlers
- Fix duplicate x-on:click attribute on uninstall button
- Add proper loading state management in loadPluginConfig method

This resolves the 'Invalid or unexpected token' and 'Uncaught ReferenceError'
errors in the browser console.

* fix(web): Fix plugin undefined errors in Alpine.js plugin configuration

- Change x-data initialization to capture plugin from loop scope first
- Use Object.assign in x-init to merge pluginConfigData properties
- Add safety check in pluginConfigData function for undefined plugins
- Ensure plugin is available before accessing properties in expressions

This resolves the 'Cannot read properties of undefined' errors by ensuring
the plugin object is properly captured from the x-for loop scope before
any template expressions try to access it.

* style(web): Make Quick Actions button text styling consistent

- Update Start Display, Stop Display, and Reboot System buttons
- Change from text-sm font-medium to text-base font-semibold
- All Quick Actions buttons now have consistent bold, larger text
- Matches the styling of Update Code, Restart Display Service, and Restart Web Service buttons

* fix(wifi): Properly handle AP mode disable during WiFi connection

- Check return value of disable_ap_mode() before proceeding with connection
- Add verification loop to ensure AP mode is actually disabled
- Increase wait time to 5 seconds for NetworkManager restart stabilization
- Return clear error messages if AP mode cannot be disabled
- Prevents connection failures when switching networks from web UI or AP mode

This fixes the issue where WiFi network switching would fail silently when
AP mode disable failed, leaving the system in an inconsistent state.

* fix(web): Handle API response errors in plugin configuration loading

- Add null/undefined checks before accessing API response status
- Set fallback defaults when API responses don't have status 'success'
- Add error handling for batch API requests with fallback to individual requests
- Add .catch() handlers to individual fetch calls to prevent unhandled rejections
- Add console warnings to help debug API response failures
- Fix applies to both main loadPluginConfig and PluginConfigHelpers.loadPluginConfig

This fixes the issue where plugin configuration sections would get stuck
showing the loading animation when API responses failed or returned error status.

* fix(web): Fix Alpine.js reactivity for plugin config by using direct x-data

Changed from Object.assign pattern to direct x-data assignment to ensure
Alpine.js properly tracks reactive properties. The previous approach used
Object.assign to merge properties into the component after initialization,
which caused Alpine to not detect changes to config/schema properties.

The fix uses pluginConfigData(plugin) directly as x-data, ensuring all
properties including config, schema, loading, etc. are reactive from
component initialization.

* fix(web): Ensure plugin variable is captured in x-data scope

Use spread operator to merge pluginConfigData properties while explicitly
capturing the plugin variable from outer x-for scope. This fixes undefined
plugin errors when Alpine evaluates the component data.

* fix(web): Use $data for Alpine.js reactivity when merging plugin config

Use Object.assign with Alpine's $data reactive proxy instead of this to
ensure added properties are properly reactive. This fixes the issue where
plugin variable scoping from x-for wasn't accessible in x-data expressions.

* fix(web): Remove incorrect 'this.' prefix in Alpine.js template expressions

Alpine.js template expressions (x-show, x-html, x-text, x-on) use the
component data as the implicit context, so 'this.' prefix is incorrect.
In template expressions, 'this' refers to the DOM element, not the
component data.

Changes:
- Replace 'this.plugin.' with 'plugin.' in all template expressions (19 instances)
- Replace 'this.loading' with 'loading' in x-show directives
- Replace 'this.generateConfigForm' with 'generateConfigForm' in x-show/x-html
- Replace 'this.savePluginConfig' with 'savePluginConfig' in x-on:submit
- Replace 'this.config/schema/webUiActions' with direct property access
- Use '$data.loadPluginConfig' in x-init for explicit method call

Note: 'this.' is still correct inside JavaScript method definitions within
pluginConfigData() function since those run with proper object context.

* fix(web): Prevent infinite recursion in plugin config methods

Add 'parent !== this' check to loadPluginConfig, generateConfigForm, and
savePluginConfig methods in pluginConfigData to prevent infinite recursion
when the component tries to delegate to a parent that resolves to itself.

This fixes the 'Maximum call stack size exceeded' error that occurred when
the nested Alpine component's $root reference resolved to a component that
had the same delegating methods via Object.assign.

* fix(web): Resolve infinite recursion in plugin config by calling $root directly

The previous implementation had delegating methods (generateConfigForm,
savePluginConfig) in pluginConfigData that tried to call parent.method(),
but the parent detection via getParentApp() was causing circular calls
because multiple components had the same methods.

Changes:
- Template now calls $root.generateConfigForm() and $root.savePluginConfig()
  directly instead of going through nested component delegation
- Removed delegating generateConfigForm and savePluginConfig from pluginConfigData
- Removed getParentApp() helper that was enabling the circular calls
- Simplified loadPluginConfig to use PluginConfigHelpers directly

This fixes the 'Maximum call stack size exceeded' error when rendering
plugin configuration forms.

* fix(web): Use window.PluginConfigHelpers instead of $root for plugin config

The $root magic variable in Alpine.js doesn't correctly reference the
app() component's data scope from nested x-data contexts. This causes
generateConfigForm and savePluginConfig to be undefined.

Changed to use window.PluginConfigHelpers which has explicit logic to
find and use the app component's methods.

* fix(web): Use direct x-data initialization for plugin config reactivity

Changed from Object.assign($data, pluginConfigData(plugin)) to
x-data="pluginConfigData(plugin)" to ensure Alpine.js properly
tracks reactivity for all plugin config properties. This fixes
the issue where all plugin tabs were showing the same config.

* refactor(web): Implement server-side plugin config rendering with HTMX

Major architectural improvement to plugin configuration management:

- Add server-side Jinja2 template for plugin config forms
  (web_interface/templates/v3/partials/plugin_config.html)
- Add Flask route to serve plugin config partials on-demand
- Replace complex client-side form generation with HTMX lazy loading
- Add Alpine.js store for centralized plugin state management
- Mark old pluginConfigData and PluginConfigHelpers as deprecated

Benefits:
- Lazy loading: configs only load when tab is accessed
- Server-side rendering: reduces client-side complexity
- Better performance: especially on Raspberry Pi
- Cleaner code: Jinja2 macros replace JS string templates
- More maintainable: form logic in one place (server)

The old client-side code is preserved for backwards compatibility
but is no longer used by the main plugin configuration UI.

* fix(web): Trigger HTMX manually after Alpine renders plugin tabs

HTMX processes attributes at page load time, before Alpine.js
renders dynamic content. Changed from :hx-get attribute to
x-init with htmx.ajax() to properly trigger the request after
the element is rendered.

* fix(web): Remove duplicate 'enabled' toggle from plugin config form

The 'enabled' field was appearing twice in plugin configuration:
1. Header toggle (quick action, uses HTMX)
2. Configuration form (from schema, requires save)

Now only the header toggle is shown, avoiding user confusion.
The 'enabled' key is explicitly skipped when rendering schema properties.

* perf(web): Optimize plugin manager with request caching and init guards

Major performance improvements to plugins_manager.js:

1. Request Deduplication & Caching
   - Added pluginLoadCache with 3-second TTL
   - Subsequent calls return cached data instead of making API requests
   - In-flight request deduplication prevents parallel duplicate fetches
   - Added refreshInstalledPlugins() for explicit force-refresh

2. Initialization Guards
   - Added pluginsInitialized flag to prevent multiple initializePlugins() calls
   - Added _eventDelegationSetup guard on container to prevent duplicate listeners
   - Added _listenerSetup guards on search/category inputs

3. Debug Logging Control
   - Added PLUGIN_DEBUG flag (localStorage.setItem('pluginDebug', 'true'))
   - Most console.log calls now use pluginLog() which only logs when debug enabled
   - Reduces console noise from ~150 logs to ~10 in production

Expected improvements:
- API calls reduced from 6+ to 2 on page load
- Event listeners no longer duplicated
- Cleaner console output
- Faster perceived performance

* fix(web): Handle missing search elements in searchPluginStore

The searchPluginStore function was failing silently when called before
the plugin-search and plugin-category elements existed in the DOM.
This caused the plugin store to never load.

Now safely checks if elements exist before accessing their values.

* fix(web): Ensure plugin store loads via pluginManager.searchPluginStore

- Exposed searchPluginStore on window.pluginManager for easier access
- Updated base.html to fallback to pluginManager.searchPluginStore
- Added logging when loading plugin store

* fix(web): Expose searchPluginStore from inside the IIFE

The function was defined inside the IIFE but only exposed after the IIFE
ended, where the function was out of scope. Now exposed immediately after
definition inside the IIFE.

* fix(web): Add cache-busting version to plugins_manager.js URL

Static JS files were being aggressively cached, preventing updates
from being loaded by browsers.

* fix(web): Fix pluginLog reference error outside IIFE

pluginLog is defined inside the IIFE, so use _PLUGIN_DEBUG_EARLY and
console.log directly for code outside the IIFE.

* chore(web): Update plugins_manager.js cache version

* fix(web): Defer plugin store render when grid not ready

Instead of showing an error when plugin-store-grid doesn't exist,
store plugins in window.__pendingStorePlugins for later rendering
when the tab loads (consistent with how installed plugins work).

* chore: Bump JS cache version

* fix(web): Restore enabledBool variable in plugin render

Variable was removed during debug logging optimization but was still
being used in the template string for toggle switch rendering.

* fix(ui): Add header and improve categories section rendering

- Add proper header (h4) to categories section with label
- Add debug logging to diagnose categories field rendering
- Improve additionalProperties condition check readability

* fix(ui): Improve additionalProperties condition check

- Explicitly exclude objects with properties to avoid conflicts
- Ensure categories section is properly detected and rendered
- Categories should show as header with toggles, not text box

* fix(web-ui): Fix JSON parsing errors and default value loading for plugin configs

- Fix JSON parsing errors when saving file upload fields by properly unescaping HTML entities
- Merge config with schema defaults when loading plugin config so form shows default values
- Improve default value handling in form generation for nested objects and arrays
- Add better error handling for malformed JSON in file upload fields

* fix(plugins): Return plugins array from getInstalledPlugins() instead of data object

Fixed PluginAPI.getInstalledPlugins() to return response.data.plugins (array)
instead of response.data (object). This was preventing window.installedPlugins
from being set correctly, which caused plugin configuration tabs to not appear
and prevented users from saving plugin configurations via the web UI.

The fix ensures that:
- window.installedPlugins is properly populated with plugin array
- Plugin tabs are created automatically on page load
- Configuration forms and save buttons are rendered correctly
- Save functionality works as expected

* fix(api): Support form data submission for plugin config saves

The HTMX form submissions use application/x-www-form-urlencoded format
instead of JSON. This update allows the /api/v3/plugins/config POST
endpoint to accept both formats:

- JSON: plugin_id and config in request body (existing behavior)
- Form data: plugin_id from query string, config fields from form

Added _parse_form_value helper to properly convert form strings to
appropriate Python types (bool, int, float, JSON arrays/objects).

* debug: Add form data logging to diagnose config save issue

* fix(web): Re-discover plugins before loading config partial

The plugin config partial was returning 'not found' for plugins
because the plugin manifests weren't loaded. The installed plugins
API was working because it calls discover_plugins() first.

Changes:
- Add discover_plugins() call in _load_plugin_config_partial when
  plugin info is not found on first try
- Remove debug logging from form data handling

* fix(web): Comprehensive plugin config save improvements

SWEEPING FIX for plugin configuration saving issues:

1. Form data now MERGES with existing config instead of replacing
   - Partial form submissions (missing fields) no longer wipe out
     existing config values
   - Fixes plugins with complex schemas (football, clock, etc.)

2. Improved nested value handling with _set_nested_value helper
   - Correctly handles deeply nested structures like customization
   - Properly merges when intermediate objects already exist

3. Better JSON parsing for arrays
   - RGB color arrays like [255, 0, 0] now parse correctly
   - Parse JSON before trying number conversion

4. Bump cache version to force JS reload

* fix(web): Add early stubs for updatePlugin and uninstallPlugin

Ensures these functions are available immediately when the page loads,
even before the full IIFE executes. Provides immediate user feedback
and makes API calls directly.

This fixes the 'Update button does not work' issue by ensuring the
function is always defined and callable.

* fix(web): Support form data in toggle endpoint

The toggle endpoint now accepts both JSON and HTMX form submissions.
Also updated the plugin config template to send the enabled state
via hx-vals when the checkbox changes.

Fixes: 415 Unsupported Media Type error when toggling plugins

* fix(web): Prevent config duplication when toggling plugins

Changed handleToggleResponse to update UI in place instead of
refreshing the entire config partial, which was causing duplication.

Also improved refreshPluginConfig with proper container targeting
and concurrent refresh prevention (though it's no longer needed
for toggles since we update in place).

* fix(api): Schema-aware form value parsing for plugin configs

Major fix for plugin config saving issues:

1. Load schema BEFORE processing form data to enable type-aware parsing
2. New _parse_form_value_with_schema() function that:
   - Converts comma-separated strings to arrays when schema says 'array'
   - Parses JSON strings for arrays/objects
   - Handles empty strings for arrays (returns [] instead of None)
   - Uses schema to determine correct number types
3. Post-processing to ensure None arrays get converted to empty arrays
4. Proper handling of nested object fields

Fixes validation errors:
- 'category_order': Expected type array, got str
- 'categories': Expected type object, got str
- 'uploaded_files': Expected type array, got NoneType
- RGB color arrays: Expected type array, got str

* fix(web): Make plugin config handlers idempotent and remove scripts from HTMX partials

CRITICAL FIX for script redeclaration errors:

1. Removed all <script> tags from plugin_config.html partial
   - Scripts were being re-executed on every HTMX swap
   - Caused 'Identifier already declared' errors

2. Moved all handler functions to base.html with idempotent initialization
   - Added window.__pluginConfigHandlersInitialized guard
   - Functions only initialized once, even if script runs multiple times
   - All state stored on window object (e.g., window.pluginConfigRefreshInProgress)

3. Enhanced error logging:
   - Client-side: Logs form payload, response status, and parsed error details
   - Server-side: Logs raw form data and parsed config on validation failures

4. Functions moved to window scope:
   - toggleSection
   - handleConfigSave (with detailed error logging)
   - handleToggleResponse (updates UI in place, no refresh)
   - handlePluginUpdate
   - refreshPluginConfig (with duplicate prevention)
   - runPluginOnDemand
   - stopOnDemand
   - executePluginAction

This ensures HTMX-swapped fragments only contain HTML, and all
scripts run once in the base layout.

* fix(api): Filter config to only schema-defined fields before validation

When merging with existing_config, fields not in the plugin's schema
(like high_performance_transitions, transition, dynamic_duration)
were being preserved, causing validation failures when
additionalProperties is false.

Add _filter_config_by_schema() function to recursively filter config
to only include fields defined in the schema before validation.

This fixes validation errors like:
- 'Additional properties are not allowed (high_performance_transitions, transition were unexpected)'

* fix(web): Improve update plugin error handling and support form data

1. Enhanced updatePlugin JavaScript function:
   - Validates pluginId before sending request
   - Checks response.ok before parsing JSON
   - Better error logging with request/response details
   - Handles both successful and error responses properly

2. Update endpoint now supports both JSON and form data:
   - Similar to config endpoint, accepts plugin_id from query string or form
   - Better error messages and debug logging

3. Prevent duplicate function definitions:
   - Second updatePlugin definition checks if improved version exists
   - Both definitions now have consistent error handling

Fixes: 400 BAD REQUEST 'Request body must be valid JSON' error

* fix(web): Show correct 'update' message instead of 'save' for plugin updates

The handlePluginUpdate function now:
1. Checks actual HTTP status code (not just event.detail.successful)
2. Parses JSON response to get server's actual message
3. Replaces 'save' with 'update' if message incorrectly says 'save'

Fixes: Update button showing 'saved successfully' instead of
'updated successfully'

* fix(web): Execute plugin updates immediately instead of queuing

Plugin updates are now executed directly (synchronously) instead of
being queued for async processing. This provides immediate feedback
to users about whether the update succeeded or failed.

Updates are fast git pull operations, so they don't need async
processing. The operation queue is reserved for longer operations
like install/uninstall.

Fixes: Update button not actually updating plugins (operations were
queued but users didn't see results)

* fix(web): Ensure toggleSection function is always available for collapsible headers

Moved toggleSection outside the initialization guard block so it's
always defined, even if the plugin config handlers have already been
initialized. This ensures collapsible sections in plugin config forms
work correctly.

Added debug logging to help diagnose if sections/icons aren't found.

Fixes: Collapsible headers in plugin config schema not collapsing

* fix(web): Improve toggleSection to explicitly show/hide collapsible content

Changed from classList.toggle() to explicit add/remove of 'hidden' class
based on current state. This ensures the content visibility is properly
controlled when collapsing/expanding sections.

Added better error checking and state detection for more reliable
collapsible section behavior.

* fix(web): Load plugin tabs on page load instead of waiting for plugin manager tab click

The stub's loadInstalledPlugins was an empty function, so plugin tabs
weren't loading until the plugin manager tab was clicked. Now the stub
implementation:
1. Tries to use global window.loadInstalledPlugins if available
2. Falls back to window.pluginManager.loadInstalledPlugins
3. Finally falls back to direct loading via loadInstalledPluginsDirectly
4. Always updates tabs after loading plugins

This ensures plugin navigation tabs are available immediately on page load.

Fixes: Plugin tabs only loading after clicking plugin manager tab

* fix(web): Ensure plugin navigation tabs load on any page regardless of active tab

Multiple improvements to ensure plugin tabs are always visible:

1. Stub's loadInstalledPluginsDirectly now waits for DOM to be ready
   before updating tabs, using requestAnimationFrame for proper timing

2. Stub's init() now has a retry mechanism that periodically checks
   if plugins have been loaded by plugins_manager.js and updates tabs
   accordingly (checks for 2 seconds)

3. Full implementation's init() now properly handles async plugin loading
   and ensures tabs are updated after loading completes, checking
   window.installedPlugins first before attempting to load

4. Both stub and full implementation ensure tabs update using $nextTick
   to wait for Alpine.js rendering cycle

This ensures plugin navigation tabs are visible immediately when the
page loads, regardless of whether the user is on overview, plugin manager,
or any other tab.

Fixes: Plugin tabs only appearing after clicking plugin manager tab

* fix(web): Fix restart display button not working

The initPluginsPage function was returning early before event listeners
were set up, making all the event listener code unreachable. Moved the
return statement to after all event listeners are attached.

This fixes the restart display button and all other buttons in the
plugin manager (refresh plugins, update all, search, etc.) that depend
on event listeners being set up.

Fixes: Restart Display button not working in plugin manager

* fix(web-ui): Improve categories field rendering for of-the-day plugin

- Add more explicit condition checking for additionalProperties objects
- Add debug logging specifically for categories field
- Add fallback handler for objects that don't match special cases (render as JSON textarea)
- Ensure categories section displays correctly with toggle cards instead of plain text

* fix(install): Prevent following broken symlinks during file ownership setup

- Add -P flag to find commands to prevent following symlinks when traversing
- Add -h flag to chown to operate on symlinks themselves rather than targets
- Exclude scripts/dev/plugins directory which contains development symlinks
- Fixes error when chown tries to dereference broken symlinks with extra LEDMatrix in path

* fix(scroll): Ensure scroll completes fully before switching displays

- Add display_width to total scroll distance calculation

* fix(web): Ensure plugin navigation tabs load on any page by dispatching events

The issue was that when plugins_manager.js loaded and called
loadInstalledPlugins(), it would set window.installedPlugins but the
Alpine.js component wouldn't know to update its tabs unless the plugin
manager tab was clicked.

Changes:
1. loadInstalledPlugins() now always dispatches a 'pluginsUpdated' event
   when it sets window.installedPlugins, not just when plugin IDs change
2. renderInstalledPlugins() also dispatches the event and always updates
   window.installedPlugins for reactivity
3. Cached plugin data also dispatches the event when returned

The Alpine component already listens for the 'pluginsUpdated' event in
its init() method, so tabs will now update immediately when plugins are
loaded, regardless of which tab is active.

Fixes: Plugin navigation tabs only loading after clicking plugin manager tab

* fix(web): Improve input field contrast in plugin configuration forms

Changed input backgrounds from bg-gray-800 to bg-gray-900 (darker) to
ensure high contrast with white text. Added placeholder:text-gray-400
for better placeholder text visibility.

Updated in both server-side template (plugin_config.html) and client-side
form generation (plugins_manager.js):
- Number inputs
- Text inputs
- Array inputs (comma-separated)
- Select dropdowns
- Textareas (JSON objects)
- Fallback inputs without schema

This ensures all form inputs have high contrast white text on dark
background, making them clearly visible and readable.

Fixes: White text on white background in plugin config inputs

* fix(web): Change plugin config input text from white to black

Changed all input fields in plugin configuration forms to use black text
on white background instead of white text on dark background for better
readability and standard form appearance.

Updated:
- Input backgrounds: bg-gray-900 -> bg-white
- Text color: text-white -> text-black
- Placeholder color: text-gray-400 -> text-gray-500

Applied to both server-side template and client-side form generation
for all input types (number, text, select, textarea).

* fix(web): Ensure toggleSection function is available for plugin config collapsible sections

Moved toggleSection function definition to an early script block so it's
available immediately when HTMX loads plugin configuration content. The
function was previously defined later in the page which could cause it
to not be accessible when inline onclick handlers try to call it.

The function toggles the 'hidden' class on collapsible section content
divs and rotates the chevron icon between right (collapsed) and down
(expanded) states.

Fixes: Plugin configuration section headers not collapsing/expanding

* fix(web): Fix collapsible section toggle to properly hide/show content

Updated toggleSection function to explicitly set display style in addition
to toggling the hidden class. This ensures the content is properly hidden
even if CSS specificity or other styles might interfere with just the
hidden class.

The function now:
- Checks both the hidden class and computed display style
- Explicitly sets display: '' when showing and display: 'none' when hiding
- Rotates chevron icon between right (collapsed) and down (expanded)

This ensures collapsible sections in plugin configuration forms properly
hide and show their content when the header is clicked.

Fixes: Collapsible section headers rotate chevron but don't hide content

* fix(web): Fix collapsible section toggle to work on first click

Simplified the toggle logic to rely primarily on the 'hidden' class check
rather than mixing it with computed display styles. When hiding, we now
remove any inline display style to let Tailwind's 'hidden' class properly
control the display property.

This ensures sections respond correctly on the first click, whether they're
starting in a collapsed or expanded state.

Fixes: Sections requiring 2 clicks to collapse

* fix(web): Ensure collapsible sections start collapsed by default

Added explicit display: none style to nested content divs in plugin config
template to ensure they start collapsed. The hidden class should handle this,
but adding the inline style ensures sections are definitely collapsed on
initial page load.

Sections now:
- Start collapsed (hidden) with chevron pointing right
- Expand when clicked (chevron points down)
- Collapse when clicked again (chevron points right)

This ensures a consistent collapsed initial state across all plugin
configuration sections.

* fix(web): Fix collapsible section toggle to properly collapse on second click

Fixed the toggle logic to explicitly set display: block when showing and
display: none when hiding, rather than clearing the display style. This
ensures the section state is properly tracked and the toggle works correctly
on both expand and collapse clicks.

The function now:
- When hidden: removes hidden class, sets display: block, chevron down
- When visible: adds hidden class, sets display: none, chevron right

This fixes the issue where sections would expand but not collapse again.

Fixes: Sections not collapsing on second click

* feat(web): Ensure plugin navigation tabs load automatically on any page

Implemented comprehensive solution to ensure plugin navigation tabs load
automatically without requiring a visit to the plugin manager page:

1. Global event listener for 'pluginsUpdated' - works even if Alpine isn't
   ready yet, updates tabs directly when plugins_manager.js loads plugins

2. Enhanced stub's loadInstalledPluginsDirectly():
   - Sets window.installedPlugins after loading
   - Dispatches 'pluginsUpdated' event for global listener
   - Adds console logging for debugging

3. Event listener in stub's init() method:
   - Listens for 'pluginsUpdated' events
   - Updates component state and tabs when events fire

4. Fallback timer:
   - If plugins_manager.js hasn't loaded after 2 seconds, fetches
     plugins directly via API
   - Ensures tabs appear even if plugins_manager.js fails

5. Improved checkAndUpdateTabs():
   - Better logging
   - Fallback to direct fetch after timeout

6. Enhanced logging throughout plugin loading flow for debugging

This ensures plugin tabs are visible immediately on page load, regardless
of which tab is active or when plugins_manager.js loads.

Fixes: Plugin navigation tabs only loading after visiting plugin manager

* fix(web): Improve plugin tabs update logging and ensure immediate execution

Enhanced logging in updatePluginTabs() and _doUpdatePluginTabs() to help
debug why tabs aren't appearing. Changed debounce behavior to execute
immediately on first call to ensure tabs appear quickly.

Added detailed console logging with [FULL] prefix to track:
- When updatePluginTabs() is called
- When _doUpdatePluginTabs() executes
- DOM element availability
- Tab creation process
- Final tab count

This will help identify if tabs are being created but not visible, or if
the update function isn't being called at all.

Fixes: Plugin tabs loading but not visible in navigation bar

* fix(web): Prevent duplicate plugin tab updates and clearing

Added debouncing and duplicate prevention to stub's updatePluginTabs() to
prevent tabs from being cleared and re-added multiple times. Also checks
if tabs already match before clearing them.

Changes:
1. Debounce stub's updatePluginTabs() with 100ms delay
2. Check if existing tabs match current plugin list before clearing
3. Global event listener only triggers full implementation's updatePluginTabs
4. Stub's event listener only works in stub mode (before enhancement)

This prevents the issue where tabs were being cleared and re-added
multiple times in rapid succession, which could leave tabs empty.

Fixes: Plugin tabs being cleared and not re-added properly

* fix(web): Fix plugin tabs not rendering when plugins are loaded

Fixed _doUpdatePluginTabs() to properly use component's installedPlugins
instead of checking window.installedPlugins first. Also fixed the 'unchanged'
check to not skip when both lists are empty (first load scenario).

Changes:
1. Check component's installedPlugins first (most up-to-date)
2. Only skip update if plugins exist AND match (don't skip empty lists)
3. Retry if no plugins found (in case they're still loading)
4. Ensure window.installedPlugins is set when loading directly
5. Better logging to show which plugin source is being used

This ensures tabs are rendered when plugins are loaded, even on first page load.

Fixes: Plugin tabs not being drawn despite plugins being loaded
